Detailed Description

Contains the simple take example for Legion ownership acquisition.

To start, no entity is simulated. The invocation of a requestAcquisition service is manually triggered via the command prompt (pressing the 't' key). The request is not made unless there are entities available to be taken. After acquiring an entity via the OwnershipAcquired callback, the entity is simulated to move to a destination. Upon reaching the destination, the entity is destroyed and a new cycle of acquiring and simulating can be initiated. A simulating entity may be preemptively destroyed by pressing the 'd' key.
