Parses strings of the form -10--5,-2-10,12-12 . Spaces are allowed, no other characters are. If mergeOverlappingRanges, then, for example, 2-3,4-5 is represented as 2-5. Otherwise, they're maintained as separate ranges. The only difference is in the behavior of the ToString() call. By extension, this will change how a RangeCollection is parsed into a RangeCollectionCollection using the latter's GetInstance(RangeCollection) initializer.
