// Purpose: One ControlPointMaster is spawned per level. Shortly after spawning it detects all the Control
// points in the map and puts them into the m_ControlPoints. From there it detects the state 
// where all points are captured and resets them if necessary It gives points every time interval to 
// the owners of the points
