FUNCTION _WILDCARD()

  Short:
  ------
  _WILDCARD() Wild Card String Compare

  Returns:
  --------
  <lMatched> => match

  Syntax:
  -------
  _wildcard(<cPattern>,<cTarget>)

  Description:
  ------------
  <cPattern> is a model/wildcard pattern to search for
  and <cTarget> is a string to compare with model/pattern in
  <cPattern>.

  Like DOS wildcards, but for a string.

  <cPattern> is a string of wild cards interspersed
  with literal text to compare against the contents of <cTarget>.
  The following conventions for wild cards are followed:

    1. "*"     stands for any group of characters.

                W*r     gives fields beginning with
                     "W", ending with "r".
                *w*r    gives fields having "w"
                    before last character "r".

    2. "?"     stands for any single character.
                J?n?s   gives Janes, Janus, Jones, and so
                on.

  Examples:
  ---------
   _wildcard("Pr?fon*e", "Prefontaine" )
   // returns -> True

   _wildcard("Pr?on*e", "Prefontaine" )
   // returns -> False

   _wildcard("Stei*er","Prefontaine")
   // returns -> False

  Notes:
  -------
  This was a C function in previous SuperLibs. Now 5.01
  Clipper source code, and more reliable.
