Detailed Description

DtOrbitTask represents an orbit task for an entity to perform.

It inherits read/writableness from SimTask, and includes the center point to orbit, the radius at which to orbit, and flag indicating clockwise or counter clockwise.

Only individual entities can receive this task. This task is never complete, and is only stopped when the entity is destroyed or re-tasked.
