=head1 NAME
UR::BoolExpr::Template::PropertyComparison::Like - perform an SQL-ish like test
=head1 DESCRIPTION
The input test value is assummed to be an SQL 'like' value, where '_'
represents a one character wildcard, and '%' means a 0 or more character
wildcard. It gets converted to a perl regular expression and used to match
against an object's properties.
If the property returns multiple values, this comparison returns true if any of the values
match.
