Subject: - New trait HasBinaryPoint which provides literal values as double
 and big decimal - made .F and .I work for creating fixed point and interval
 lits from big decimal - Added NumObject trait which provides new math
 conversions - Made a Num object that extends NumObject - Add this trait to
 FixedPoint and Interval for backward compatibility - Removed code that is now
 in NumObject, keeping things DRY - Add tests to FixedPointSpec to show lit
 conversion to double and big decimal - Add tests to IntervalSpec to show lit
 conversion to double and big decimal - Add tests to LiteralExtractorSpec to
 show general math conversions between BigInts with binary points and double
 and big decimal
