Open

The specification states:

The base glyph referenced by a component may contain components. The base glyph must not create a circular reference to the glyph that contains the component. Components must only reference glyphs within the same layer that the component belongs to.

ufoLib currently does not validate this. Should it? Should ufoLib2?

Probably ufoLib if that's where most of the validation logic is already?
