[jessicamillar]

• Types require Version (as literal)
• Create type_helper/init.py for non-derived objects in types folder
• Type attributes that are enums do not specify enum version
• Reference local gridworks type registry enum from types, instead of including in local file
• Generally clean up the readibility of derived types
• Introduce concept of Application/Actor Shared Languages (ASLs)
• Restructure airtable so key words are aligned with code (e.g. Schema -> Type, SchemaAlias -> TypeName)

Fix key typo fail in electric meter components and fix test that did not catch it
