 If an entity is created without an ur, is ur is defined as its given text and data. It cannot be saved. It must be given a new ur name.
 
+Objects can be composed on the fly by stringing together urs. For example, a "2x.json" might define scale as 2x. Then, you can create a goblin with `ur.goblin`, or a large goblin with `ur.goblin.2x`. This creates a goblin object, and then applies the 2x scripts and jsons onto the object.

 Each ur has the following fields.
