name and otherName parameters to SassNumber.convert*() and
SassNumber.coerce*() methods so that they can provide additional debugging
information.toString() method to Value.name parameters to Value.sassIndexToListIndex() and
SassString.sassIndexToStringIndex().Add name parameters to assert*() methods so that they can provide
additional debugging information.
Value.assertMap() now returns an empty SassMap when called on an empty list.
Renamed Value.asMap() to Value.tryMap() to help distinguish it from the
asList getter.
Value.hashCode() now returns a number to match the behavior expected by the
immutable package.
Removed SassFunction.signature since this couldn't be implemented for
built-in functions.
Added SassMap.tryMap() to override Value.tryMap() and declare statically
that it never returns null.
Make Value explicitly implement the immutable package's ValueType
interface.
