public class ProperFractionFormat extends FractionFormat
Minus signs are only allowed in the whole number part - i.e.,
"-3 1/2" is legitimate and denotes -7/2, but "-3 -1/2" is invalid and
will result in a ParseException.

public Fraction parse(String source, ParsePosition pos)
Fraction object. This method
expects the string to be formatted as a proper fraction.
Minus signs are only allowed in the whole number part - i.e.,
"-3 1/2" is legitimate and denotes -7/2, but "-3 -1/2" is invalid and
will result in a ParseException.
