C++ and Java implementations should treat unsupported Types in the same way

[thomasheritage]

I've not fully explored this but it would appear that the C++ implementation will import Integer Types regardless of Type Size and then only throw an exception about an unsupported Type Size in the Fragment Builder. See:

• Importer
• Fragment Builder

This presumably means that if Integer Types with unsupported Type Size values exist in the Types Register then the Reg-XML dictionaries produced by the two implementations will be different. This is presumably undesirable (although I don't know if other differences already exist).

This arises from #146
