Communicate Action implementation and testing

[renardyreveur]

Create a rule based policy like the one used for 'tag' and test out the communication mechanism

• Try with 3 or more agents in the same team, see if simultaneous comms come in as a list, etc.
• See if each agent's comm variable is updated accurately, etc.
• Try adjusting the agent's actions based on the communication results.
• e.g) If communication received, for the next three steps, head towards the communication origin, if multiple comms at the same time, head to closest agent, etc

The latest commit: a0ba833abc94b96ea85ba4bdb89205a79e0f6a35 also adds some communication event test logic.

One agent stays still, and the others will find the agent and go towards it. Simultaneous communication checked and agent behaviour checked.

Closing the issue as the initial implementation is done! :+1:
