=head1 NAME

parserFormulaWithUnits.pl - Implements a formula with units.

=head1 DESCRIPTION

This is a Parser class that implements a formula with units.
It is a temporary version until the Parser can handle it
directly.

Use FormulaWithUnits("num units") or FormulaWithUnits(formula,"units")
to generate a FormulaWithUnits object, and then call its cmp() method
to get an answer checker for your formula with units.

=head1 USAGE

	ANS(FormulaWithUnits("3x+1 ft")->cmp);
	ANS(FormulaWithUnits("$a*x+1 ft")->cmp);

	$x = Formula("x");
	ANS(FormulaWithUnits($a*$x+1,"ft")->cmp);

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