/**
This is the interface of the Communicators.
This does not need to be modified nor implemented to create a Unity environment.
When the Unity Communicator is initialized, it will wait for the External Communicator
to be initialized as well. The two communicators will then exchange their first messages
that will usually contain information for initialization (information that does not need
to be resent at each new exchange).
By convention a Unity input is from External to Unity and a Unity output is from Unity to
External. Inputs and outputs are relative to Unity.
By convention, when the Unity Communicator and External Communicator call exchange, the
exchange is NOT simultaneous but sequential. This means that when a side of the
communication calls exchange, the other will receive the result of its previous
exchange call.
This is what happens when A calls exchange a single time:
A sends data_1 to B -> B receives data_1 -> B generates and sends data_2 -> A receives data_2
When A calls exchange, it sends data_1 and receives data_2
Since the messages are sent back and forth with exchange and simultaneously when calling
initialize, External sends two messages at initialization.
The structure of the messages is as follows:
UnityMessage
...Header
...UnityOutput
......UnityRLOutput
......UnityRLInitializationOutput
...UnityInput
......UnityRLIntput
......UnityRLInitializationIntput
UnityOutput and UnityInput can be extended to provide functionalities beyond RL
UnityRLOutput and UnityRLInput can be extended to provide new RL functionalities
