Refactor a bunch of the logic in matrix_templates/units.py

Browse Source 
Move 'inherit_parents' calls up to before get_json_schema_object_fields so that
things can inherit their types via allOf declarations. Also make it possible to
inherit descriptions.

Remove redundant 'include_parents' parameter, which was never used.

Move 'resolve_references' call out of get_tables_for_schema (it was redundant
sometimes and not others, and now it is clearer who has responsibility for it)
