Allow Inheritance of Prebuilt Entities
Allow the user to make a child entity of a prebuilt entity such as money, date, etc. This would allow multiple values to be identified uniquely and so referenced easily in requests. Such as having a "startDate" and an "endDate" which don't need to be trained separately by the user.
This is now supported by being able to add role to prebuilt entities and to all other entity types.
