% \@startsection 
% {NAME}{LEVEL}{INDENT}{BEFORESKIP}{AFTERSKIP}{STYLE}
%            optional * [ALTHEADING]{HEADING}
%    Generic command to start a section.
%    NAME       : e.g., `subsection'
%    LEVEL      : a number, denoting depth of 
%                 section -- e.g., chapter=1,
%                 section = 2, etc.
%    INDENT     : Indentation of heading from 
%                 left margin
%    BEFORESKIP : Absolute value = skip to leave 
%                 above the heading.
%                 If negative, then paragraph 
%                 indent of text following heading 
%                 is suppressed.
%    AFTERSKIP  : if positive, then skip to leave 
%                 below heading, else negative of 
%                 skip to leave to right of run-in 
%                 heading.
%    STYLE      : commands to set style
%  If `*' missing, then increments the counter.  
%  If it is present, then there should be no 
%  [ALTHEADING] argument.  Uses the counter 
%  `secnumdepth' whose value is the highest 
%  section level that is to be numbered.
