%$%  Revision 2.0  95/03/06  12:43:14  sdc
%$%  This version of `subfigure' is the first to be ported to LaTeX2e
%$%  (with backward compatibility to LaTeX 2.09).  "\subfigure" and
%$%  "\subtable" are now identical and the environment controls
%$%  internal differences between them.  Now, the caption setting
%$%  portion of "\@subfloat" is broken into the separate macros
%$%  "\@makesubfigurecaption" and "\@makesubtablecaption" to allow a
%$%  separate hook for the modification of how the caption is
%$%  constructed and to allow the table and figure captions to be
%$%  different.  In addition, support of the `normal', `hang',
%$%  `center', `centerlast', 'nooneline'; `scriptsize', \ldots,
%$%  `Large'; `up', `it', `sl', `sc', `md', `bf', `rm', `sf', and `tt'
%$%  package options were added for compatibility with the caption.sty
%$%  by H.A. Sommerfeldt.}  
%$%  
%$%  Revision 1.6  93/05/13  12:58:34  sdc
%$%  Changed to use the \thefigure macro in building the referenced
%$%  label.  The old form caused a problem when used with the
%$%  report.sty as pointed out by Andrew Anselmo
%$%  (anselmo@cumesb.mech.columbia.edu).  Also modified to restrict
%$%  the scope of the subfigure \label to the body of the subfigure.
%$%  Added \@thesubfigure to allow a separate labeling of the
%$%  subfigure in the figure and in the text.  By default it is the
%$%  same as \thesubfigure with space appended.  Added some hooks to
%$%  print the subfigure captions to the list-of-figures file if
%$%  desired.  Finally, added the corresponding support for sub-tables
%$%  as well as sub-figures.  NOTE: the optional caption is now a
%$%  moving argument and any fragile commands that appear in the
%$%  caption must be preceded by a \protect (just like that of the
%$%  \caption command).
%$%   
%$%  Revision 1.5  92/08/11  23:13:12  sdc
%$%  Fixed a bug which caused an problem with captions that contained  
%$%  expressions like \sqrt;  This was pointed out by Tom Scavo
%$%  (scavo@cie.uoregon.edu).  A separate bug was fixed which caused
%$%  different sized captions to be misaligned;  This problem was
%$%  pointed out by Simon Marshall (S.Marshal@Hull.ac.uk).  Also
%$%  cleaned up the code a mite and *changed* the figure spacing so that
%$%  if no optional section is given, then the figure is only followed
%$%  by \subfigbottomskip and not that plus (\subfigcapskip + \strut
%$%  height).  This should make it easier to adjust spacing as desired.
%$%   
%$%  Revision 1.4  92/06/27  10:40:34  sdc
%$%  Added a hack to allow the \label command to be used within the
%$%  body of the subfigure giving a reference label in the form
%$%  \arabic{thefigure}\thesubfigure.  Added standard file header for
%$%  style.  
%$%   
%$%  Revision 1.3  90/10/22  17:04:28  cochran
%$%  Changed test for empty caption inside of \@subfigure to compare
%$%  tokens and not the caption vs. \@empty.  The former (incorrect)
%$%  test caused an error when the first two letters of the caption
%$%  were the same.
%$%
%$%  Revision 1.2  89/08/30  07:18:29  cochran
%$%  Added a separate bottom margin and expanded the comments.

%$%
%$%             \subfigure[CAPTIONtext]{FIGUREbox}
%%%
%%% Creates a subfigure box with an optional CAPTION under a FIGURE.
%%% The FIGURE is centered with \subfigtopskip of vertical space added
%%% above.  If there is a CAPTION, then \subfigcapskip vertical space
%%% is added below the FIGURE followed by the CAPTION.  Finally,
%%% \subfigbottomskip of vertical space added at the bottom.  
%%%
%%% If a CAPTION is given (including a null CAPTION `[]') then the
%%% subfigure is labeled with a counter formatted by the macro
%%% `\thesubfigure' which returns `(a)', `(b)', etc.  If desired,
%%% this macro may be redefined.  The counter used for labeling the
%%% subfigures is `subfigure' and is incremented for each subfigure
%%% regardless of whether a CAPTION was printed.
%%%
%$%             \subfigure[CAPTIONtext]{FIGUREbox}
%%%
%%% The subtable command is symmetric to the subfigure command defined
%%% above.   
%%%
%%% One example of use is to surround the figure in a center
%%% environment or to specifying \centering:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%% Options:
%%%
%%%  I. Subfloat caption shape.
%%%     By default the caption paragraphs are centered under the
%%%     subfigure or table with a little indentation at each side.
%%%     There are three options that may be used to change the shape
%%%     of the centered paragraph -- they only have an effect when the
%%%     caption is more than one line long.  These should be set in
%%%     the preamble of your LaTeX file:
%%%     
%%%          \subcaphangtrue        Causes the label to be a hanging
%%%                                 indentation to the caption paragraph.
%%%          \subcapcentertrue      Causes each line of the paragraph
%%%                                 to be separately centered.
%%%          \subcapcenterlasttrue  Causes the last line only to be 
%%%                                 centered.
%%%          \subcapnooneline       If a caption fits on one line it
%%%                                 will, by default, be centered.
%%%                                 This option left-justifies the one
%%%                                 line caption.
%%%
%%%     The hang option may be used in addition to either center
%%%     option.  (If both center options are true it is the same as if
%%%     only the \subcapcenter was true.)
%%%     
%%%     
%%% II. Subfloat label font.
%%%     The subfloat label font may be separately set by changing the
%%%     definition of \subcaplabelfont.  For example:
%%%     
%%%          \newcommand{\subcaplabelfont}{\it}
