   @brief
      Static resource manager synchronized across all Milton threads, 
   containing references to loaded images, global logging utilities, and 
   user-definable options which may be used to affect Milton functionality.
   Many user-definable options that are supported are aimed at dynamic, 
   on-the-fly debugging changes (whether or not to preview kd-Trees built 
   from Meshes, for instance)
