% \section{Introduction}
% \subsection{Counting Metric First-order Temporal Logic}
%  \emph{Counting Metric First-order Temporal Logic} (CMFTBL) argues about
%  finite traces of states. It is an extension of \emph{Metric First-order
%  Temporal Logic} (MFOTL), which itself is based on \emph{Metric Temporal
%  Logic} (MTL) and ultimately on \emph{Linear Temporal Logic} (LTL). All these
%  logics extend the base with further operators and features.
%
% \subsection{Basic usage}
%  This package defines the symbols used in Temporal logics as
%  \emph{MathOperators}. Therefore, the symbols, as well as the commands, have
%  to be used in math mode. To use normal text in the parameters \cs{mathrm}
%  or \cs{text} may be used to switch back to text mode.
%
%  The symbols come in two variants. A standalone version for mentioning logic
%  symbols in text without additional formula spacing is described in
%  Sect.~\ref{sec:standalone_symbols} and a formula version, also providing
%  additional parameters, is described in Sect.~\ref{sec:future_ltl} --
%  Sect.~\ref{sec:cmftbl_extension}. The formula version should always be
%  preferred over the standalone symbols in formulas as they provide
%  additional spaces and explicitly enforce the correct usage of superscript
%  and subscript via mandatory parameters. The naming scheme of the operators
%  is chosen such that each command reflects the name of the temporal operator
%  prefixed with a ``c'' for \textit{\underline{C}MFTBL}. Standalone symbols, as described
%  in Sect.~\ref{sec:standalone_symbols}, are prefixed with ``csymb''. Those
%  prefixes are necessary to prevent name clashes with built-in \LaTeX commands.
%
% \subsection{Manual structure}
%  This manual is structured as follows. First, the symbols for \emph{Future
%  LTL} and \emph{Past LTL} are introducted in Sect.~\ref{sec:future_ltl} and
%  Sect.~\ref{sec:past_ltl}. The additional intervals from \emph{MTL} are
%  described in Sect.~\ref{sec:mtl_extension}. The operators introduced
%  in \emph{MFOTL} and \emph{CMFTBL} are described in
%  Sect.~\ref{sec:mfotl_extension} and Sect.~\ref{sec:cmftbl_extension}.
%  Section~\ref{sec:usage} shows the usage of the symbols in formulas.
%  Section~\ref{sec:standalone_symbols} closes the
%  command definitions with the standalone symbols for usage in text.
%  Finally, Sect.~\ref{sec:operator_scaling} demonstrates the automatic scaling
%  of the operators.
%
% \subsection{Dependencies}
%   The package loads the following dependencies:
%   \begin{itemize}
%     \item \emph{expl3} For \LaTeX 3 support.
%     \item \emph{xparse} For parsing the mandatory and optional arguments.
%     \item \emph{amsmath} For symbol definitions.
%     \item \emph{tikz} For rendering of symbols.
%   \end{itemize}
%
% \clearpage
% \section{Symbol definitions}
% \subsection{Future LTL symbols}
% \label{sec:future_ltl}
%   \emph{Future LTL}, or simply \emph{LTL}, defines operators to argue about
%   the future. This includes the following operators.
% \begin{function}{
%   \ceventually,
%   \cglobally,
%   \cnext,
%   \cuntil}
%   \begin{syntax}
%   \begin{tabular}{lc}
%     \cs{ceventually} &amp; $\ceventually$\\
%     \cs{cglobally}   &amp; $\cglobally$\\
%     \cs{cnext}       &amp; $\cnext$\\
%     \cs{cuntil}      &amp; $\cuntil$\\
% \end{tabular}
% \end{syntax}
% \end{function}
%
%  \noindent The semantics of the operators are commonly defined as follows:
% \begin{itemize}
%   \item $\ceventually \phi$ expresses that $\phi$ must hold at least once in
%   the future.
%  \item $\cglobally \phi$ expresses that $\phi$ must hold from now for the
%   entire trace.
%  \item $\cnext \phi$ expresses that $\phi$ must hold at the next state.
%  \item $\phi \cuntil \psi$ expresses that $\phi$ must hold until $\psi$
%   holds.
% \end{itemize}
%
% \subsection{Past LTL symbols}
% \label{sec:past_ltl}
%  \emph{Past LTL} defines operators analogous to \emph{Future LTL} to argue
%  about the past. The symbols are identical but are filled solid black.
%  \begin{function}{ ,
%   \conce,
%   \chistorically,
%   \cprevious,
%   \csince}
%   \begin{syntax}
%   \begin{tabular}{lc}
%     \cs{conce}         &amp; $\conce$\\
%     \cs{chistorically} &amp; $\chistorically$\\
%     \cs{cprevious}     &amp; $\cprevious$\\
%     \cs{csince}        &amp; $\csince$\\
%   \end{tabular}
%   \end{syntax}
%  \end{function}
%
%  \noindent The semantics of the operators are commonly defined as follows:
%  \begin{itemize}
%   \item $\conce \phi$ expresses that $\phi$ must have held at least once
%   in the past.
%   \item $\chistorically \phi$ expresses that $\phi$ must have held until
%   now for the entire past trace.
%   \item $\cprevious \phi$ expresses that $\phi$ must have held at the previous
%   state.
%   \item $\phi \csince \psi$ expresses that $\phi$ must have held since $\psi$
%   has held.
%  \end{itemize}
%
% \clearpage
% \subsection{MTL extension}
% \label{sec:mtl_extension}
%  The \emph{Future LTL} and \emph{Past LTL} operators may be extended with an
%  optional interval to form \emph{MTL}.
%  \begin{function}{
%   \ceventually,
%   \conce,
%   \cglobally,
%   \chistorically,
%   \cnext,
%   \cprevious,
%   \cuntil,
%   \csince}
%   \begin{syntax}
%    \begin{tabular}{lc}
%     \cs{ceventually}\oarg{Interval} &amp; $\ceventually[[0,1]]$\\
%     \cs{conce}\oarg{Interval} &amp; $\conce[[0,1]]$\\
%     \cs{cglobally}\oarg{Interval} &amp; $\cglobally[[0,1]]$\\
%     \cs{chistorically}\oarg{Interval} &amp; $\chistorically[[0,1]]$\\
%     \cs{cnext}\oarg{Interval} &amp; $\cnext[[0,1]]$\\
%     \cs{cprevious}\oarg{Interval} &amp; $\cprevious[[0,1]]$\\
%     \cs{cuntil}\oarg{Interval} &amp; $\cuntil[[0,1]]$\\
%     \cs{csince}\oarg{Interval} &amp; $\csince[[0,1]]$\\
%   \end{tabular}
%  \end{syntax}
% \end{function}
%
%  \noindent The semantics of the intervals are commonly defined as follows:
%  The trace is only evaluated in the given interval. An empty interval is
%  considered to be $[0, \infty)$ for future and $(\infty, 0]$ for past
%  operators. The first component of the interval always indicates the earlier
%  state for both future and past operators.
%
% \subsection{MFOTL extension}
% \label{sec:mfotl_extension}
%  \emph{MFOTL} introduces the first-order quantifiers $\exists$ and $\forall$.
%  This package does not provide additional symbols, as the built-in ones
%  already contained in \LaTeX~may be used.
%
%  \begin{function}{
%   \exists,
%   \forall}
%   \begin{syntax}
%    \begin{tabular}{lc}
%     \cs{exists} &amp; $\exists$\\
%     \cs{forall} &amp; $\forall$\\
%    \end{tabular}
%   \end{syntax}
%  \end{function}
%
% \clearpage
% \subsection{CMFTBL extension}
% \label{sec:cmftbl_extension}
%  \emph{CMFTBL} extends \emph{MFOTL} by the operators \emph{minPrevalence},
%  \emph{maxPrevalence}, their past forms, and the \emph{bind} operator.
%
%  \begin{function}{
%   \cminprevalence,
%   \cpastminprevalence,
%   \cmaxprevalence,
%   \cpastmaxprevalence,
%   \cbind}
%   \begin{syntax}
%    \begin{tabular}{lc}
%     \cs{cminprevalence}\marg{Percentage}\oarg{Interval} &amp;
%     $\cminprevalence{0.8}[[0,1]]$\\
%     \cs{cpastminprevalence}\marg{Percentage}\oarg{Interval} &amp;
%     $\cpastminprevalence{0.8}[[0,1]]$\\
%     \cs{cmaxprevalence}\marg{Percentage}\oarg{Interval} &amp;
%     $\cmaxprevalence{0.8}[[0,1]]$\\
%     \cs{cpastmaxprevalence}\marg{Percentage}\oarg{Interval} &amp;
%     $\cpastmaxprevalence{0.8}[[0,1]]$\\
%     \cs{cbind}\marg{Valuation}\marg{Variable} &amp;
%     $\cbind{v.id}{i}$\\
%    \end{tabular}
%   \end{syntax}
%  \end{function}
%
%  \noindent The semantics of the operators are defined as follows. Let $p$ be a
%  fraction of states in the interval $[0,1]$:
%  \begin{itemize}
%   \item $\cminprevalence{p}[I] \phi$ expresses that $\phi$ must hold in at
%   least fraction $p$ of the future states in the interval $I$.
%   \item $\cpastminprevalence{p}[I] \phi$ expresses that $\phi$ must have held
%   in at least fraction $p$ of the past states in the interval $I$.
%   \item $\cmaxprevalence{p}[I] \phi$ expresses that $\phi$ must hold in at
%   most fraction $p$ of the future states in the interval $I$.
%   \item $\cpastmaxprevalence{p}[I] \phi$ expresses that $\phi$ must have held
%   in at most fraction $p$ of the past states in the interval $I$.
%   \item $\cbind{v.id}{i}$ saves the valuation $v.id$ to the variable $i$ for
%   later use in a nested formula, where $v$ already has a new value.
%  \end{itemize}
%
%  \emph{minPrevalence} and \emph{maxPrevalence} take the desired precentage as
%  another mandatory parameter. These operators may only be defined on finite
%  traces since they argue about numbers of states. \emph{bind} has no optional
%  interval but two mandatory arguments: the value to bind and the target
%  variable.
%
% \section{Usage in formulas}
% \label{sec:usage}
%  The commands may be directly used in math mode to create composite formulas.
%  For the unary formulas, the term $\phi$ should directly follow the symbol:
%  \begin{syntax}
%   \begin{tabular}{ll}
%    \cs{ceventually}\cs{phi} &amp; $\ceventually \phi$\\
%    \cs{cglobally}[[0,1]]\cs{phi} &amp; $\cglobally[[0,1]] \phi$
%   \end{tabular}
%  \end{syntax}
%
%  \noindent The binary symbols \emph{until} and \emph{since} should be used
%  with two formulas $\phi$ and $\psi$ directly before and after the symbol:
%  \begin{syntax}
%   \begin{tabular}{ll}
%    \cs{phi}\cs{cuntil}\cs{psi} &amp; $\phi \cuntil \psi$\\
%    \cs{phi}\cs{csince}[[0,1]]\cs{psi} &amp; $\phi \csince[[0,1]] \psi$
%   \end{tabular}
%  \end{syntax}
%
% \noindent
% The new \emph{CMFTBL} operators my be used as the unary ones:
% \begin{syntax}
% \begin{tabular}{ll}
%   \cs{cminprevalence}\{0.8\}\cs{phi} &amp;
%   $\cminprevalence{0.8} \phi$\\
%   \cs{cmaxprevalence}\{0.8\}[[0,1]]\cs{phi} &amp;
%   $\cmaxprevalence{0.8}[[0,1]] \phi$\\
%   \cs{cbind}\{v.id\}\{i\}\cs{phi} &amp;
%   $\cbind{v.id}{i} \phi$
% \end{tabular}
% \end{syntax}
%
% \section{Standalone symbols}
% \label{sec:standalone_symbols}
% The package defines all symbols as a standalone version as
% \emph{MathOperators} without additional spacing around for the usage in text.
%
% \begin{function}{
%   \csymbeventually,
%   \csymbonce,
%   \csymbglobally,
%   \csymbhistorically,
%   \csymbnext,
%   \csymbprevious,
%   \csymbuntil,
%   \csymbsince,
%   \csymbminprevalence,
%   \csymbpastminprevalence,
%   \csymbmaxprevalence,
%   \csymbpastmaxprevalence,
%   \csymbbind}
%   \begin{syntax}
%   \begin{tabular}{lc}
%     \cs{csymbeventually} &amp; $\csymbeventually$\\
%     \cs{csymbonce} &amp; $\csymbonce$\\
%     \cs{csymbglobally} &amp; $\csymbglobally$\\
%     \cs{csymbhistorically} &amp; $\csymbhistorically$\\
%     \cs{csymbnext} &amp; $\csymbnext$\\
%     \cs{csymbprevious} &amp; $\csymbprevious$\\
%     \cs{csymbuntil} &amp; $\csymbuntil$\\
%     \cs{csymbsince} &amp; $\csymbsince$\\
%     \cs{csymbminprevalence} &amp; $\csymbminprevalence$\\
%     \cs{csymbpastminprevalence} &amp; $\csymbpastminprevalence$\\
%     \cs{csymbmaxprevalence} &amp; $\csymbmaxprevalence$\\
%     \cs{csymbpastmaxprevalence} &amp; $\csymbpastmaxprevalence$\\
%     \cs{csymbbind} &amp; $\csymbbind$
% \end{tabular}
% \end{syntax}
% \end{function}
%
% \section{Operator scaling}
% \label{sec:operator_scaling}
% The operators scale automatically with the current text size:\\[\baselineskip]
%
% \begin{tabular}{ll}
