Relations Module

@x1250 The Schemas dependency is essential to the design of the module, otherwise it wouldn’t know which tables are related to others and they nature of their relationship. If you don’t like the database-scanning nature of Schemas you can still define you schema in a single flat file using the DirectoryHandler. If you have other concerns about Schemas I’m open to hearing them.

@BasicApp the constructor isn’t essential but the code it runs needs to happen - I could move it to an init() function of some sort but then either you would be responsible for initializing or it would have to be checked on every method call. I’m open to input.
