 - `default_value` (optional, only for Encodable Messages), float representing the default value to be sent before a command is received or when an empty command is received. This is ignored when decoding the Point (`0` by default)

 #### Sim
 Within the `sim` member of a NetField object, there is a single sim object.  This object is one of two types, either `sweep` or `enum`.  However these types are implied, not written in the JSON, just use them correctly!
