StringOrInteger class abstract interface

An interface for a value representing String, int or BigInt data.

The optimal situation for representing integers would be just to use int. For Dart 2 it's 64 bit integer on VM enviroment. However in web enviroment (compiled with dart2js) it supports "all integers between -2^53 and 2^53, and some integers with larger magnitude". So for this reason also BigInt might be needed for storing integers out of that range.
