function s2 = s_quote ( s1, mark )

%% s_quote() "quotes" a string.
%
%  Discussion:
%
%    Actually, it simply puts the string MARK before and after the string S1.
%
%    Sometimes, when you print a string, you want to put quote marks around it.
%    This is one way to do that.
%
%  Examples:
%
%    S1        MARK  S2
%    --------  ----  ----------
%    Hi, Bob!  "     "Hi, Bob!"
%    De        Loop  LoopDeLoop
