[hibernate-dev] Metamodel tests

Just a reminder that I am on vacation this next week.

If you want this in the meantime, you just need to alter the 
org.hibernate.metamodel.spi.relational.Database#generateSchemaCreationScript 
and 
org.hibernate.metamodel.spi.relational.Database#generateDropSchemaScript 
methods.   There is a 
org.hibernate.metamodel.spi.relational.Schema#sequences collection, but 
they wont be populated using this 
generateSchemaCreationScript/generateDropSchemaScript approach, so in 
there you will need a way to find all persistent identifier generators 
(please DO NOT collect them on Database/Schema) and handle it.

Those methods will go away when I fully hook up the schema management 
tools (they are only used from SchemaExport) so don't worry about 
breaking the schema management tool code.  And the new code will add 
sequences and tables from persistent identifier generator as we discover 
them (not coded yet)

Or just wait till I get back..
