/**
  * cubicles
  *
  * This is an implementation of the Viola-Jones object detection 
  * method and some extensions.  The code is mostly platform-
  * independent and uses only standard C and C++ libraries.  It
  * can make use of MPI for parallel training and a few Windows
  * MFC functions for classifier display.
