    9 #
   10 #  This is a Parser class that implements a formula with units.
   11 #  It is a temporary version until the Parser can handle it
   12 #  directly.
   13 #
   14 #  Use FormulaWithUnits("num units") or FormulaWithUnits(formula,"units")
   15 #  to generate a FormulaWithUnits object, and then call its cmp() method
   16 #  to get an answer checker for your formula with units.
   17 #
   18 #  Usage examples:
   19 #
   20 #      ANS(FormulaWithUnits("3x+1 ft")->cmp);
   21 #      ANS(FormulaWithUnits("$a*x+1 ft")->cmp);
   22 #
   23 #      $x = Formula("x");
   24 #      ANS(FormulaWithUnits($a*$x+1,"ft")->cmp);
   25 #

   29 #  Now uses the version in Parser::Legacy::NumberWithUnits
   30 #  to avoid duplication of common code.
