Calc Constants.Changes

Draft 1.1

• Throw an error when serializing a degenerate number with complex units in a calculation.

• Clarify that we're checking for degenerate values in "Converting a Number to a Calculation".

• Use UnquotedStrings to represent unknown calculation constants rather than CalculationInterpolations/CalculationRaws.

• Don't parenthesize the right-hand side of "+" or "-" CalculationOperations when the right-hand side is a degenerate number with one or more units. Degenerate numbers are serialized to multiplication and division expressions, which always have higher precedence than addition and subtraction.
