Commented on the purpose of class options / `\thesissetup` keyvals.

% processed by the \texttt{style/mu/fithesis-base.sty} style file

% documented in Section \ref{sec:fithesis-mu-base}.

%

% The class options specify the \emph{form} of the document.

%

% \subsection{The \cs{thesissetup} macro}

% \begin{macro}{\thesissetup}

% The main public macro is the |\thesissetup|\marg{keyvals}

% command, where \textit{keyvals} is a comma-delimited list of

% key-value pairs as defined by the \textsf{keyval} package. This

% macro needs to be included prior to the beginning of a \LaTeX\ 

% document. When used, the \textit{keyvals} are processed.

% \textit{key}=\textit{value} pairs as defined by the

% \textsf{keyval} package. This macro needs to be included prior to

% the beginning of a \LaTeX\ document. When the macro is expanded,

% the \textit{key}=\textit{value} pairs are processed.

%

% Contrary to the class options, the \textit{key}=\textit{value}

% pairs of the \cs{thesissetup} macro specify metainformation about

% the document.
