ID as strings and Parsing array items (#46)

* Update entity_file.py

catches exceptions when inferring arrays back falls to treating them as strings

* Update entity_file.py

Treats ID types as strings

* Update relation_type.py

handles "ERROR - 'RelationType' object has no attribute 'start_namespace' ", when using enforce schema with out namespaces.
