%Figure 1.1: This is the debugged version of a modified caption macro
%            to produce captions with hanging indentation (like this).
%            If the caption is less than a full line, it will be
%            centered.  \isucaption is used in the same way as \caption
%            (the name may be changed).
%            The variable \captionwidth may be set to match the width
%            of a \tabular* environment.  If set inside a table or
%            figure environment, it will affect only that environment.
