//  Creates a rectangular grid of objects, starting at the origin and proceeding along the X/Z plane.
//  Useful for testing the rendering, LOD, and octree storage aspects of the system.  
//
//  Note that when creating things quickly, the entity server will ignore data if we send updates too quickly.
//  like Internet MTU, these rates are set by th domain operator, so in this script there is a RATE_PER_SECOND 
//  variable letting you set this speed.  If entities are missing from the grid after a relog, this number 
//  being too high may be the reason.
