> In order to make working with the Table API easier. It would be great to have a class that contains the supported types.
> Such that an expression could look like:
> {code}
> .select(42.cast(TableType.INT), 43.cast(TableType.DECIMAL))
> {code}
> The constants would map to the original TypeInformation object (in BasicTypeInfo, SqlTimeTypeInfo, etc.).
