% Usage:
% \simplechapter[<name>] and \simplechapterdelim{<delim>} act together
% so that any subsequent \chapter commands, for example \chapter{First}
% ... \chapter{Second}...,
% will be typeset in the style of a \section (or numbered \chapter*) as:
% <name> 1<delim> First
% ...
% <name> 2<delim> Second
%
% A subsequent \restorechapter command will reset the \chapter typesetting
% back to its default style.
%
% Note that the argument to \simplechapter is optional, and that by default
% \simplechapterdelim is defined as \newcommand{\simplechapterdelim}{}.
%
% Extending the above example:
% \simplechapter
% \chapter{First}
% ...
% \renewcommand{\simplechapterdelim}{:}
% \chapter{Second}
% ...
% \restorechapter   % restore before issuing a modified \simplechapter
% \simplechapter[Chap]
% \chapter{Third}
% ...
% \restorechapter
% \chapter{Fourth}
% ...
% Will be typeset as:
% 1 First
% ...
% 2: Second
% ...
% Chap 3: Third
% ...
% Chapter 4
% Fourth
% ...
