Interface CastSystem

public interface CastSystem

Note to myself: My initial idea was to have a method Factory1 getCastFactory(sourceTypeName, targetTypeName) which upon invocation must return an appropriate factory. However, instead of using this factory, we could use E_Cast cast(intgeger) -> double
