=head1 NAME

UR::BoolExpr::Template::PropertyComparison::NotLike - perform a negated SQL-ish like test

=head1 DESCRIPTION

The input test value is assumed 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 in a
negated match against an object's properties

If the property returns multiple values, this comparison returns false if
any of the values matches the pattern
