Same comment as per #620

I'm sorry, I can't find the vote button here but I'd like to vote this up.

I'd also like to add to the feature specification: it should be possible to use a table as a part of more than one entity.

E.g. GUIDS are used as primary keys for all the tables and there is a field that every entity has, so there is a table of 2 columns: the GUID and the common field and a record with equal GUID is created in it for every record created in another table.

Fixed in f5af64f, 644dec8

The two commits above (f5af64f and 644dec8) only add table splitting. They don't add entity splitting, so this feature request is not complete (edit: never mind, the feature requests only mentions table splitting, not entity splitting, which has a separate feature request: #620)
