Matches feet and inch numbers with and without fractions but using the american traditional feet symbol ' (single quote) and inch symbol " (double quote). Number must be on a single line by itself. Multi-line is on for testing only and should be turned off. Proceeding and following spaces are not allowed (trim first).
