 @file    pomdpCassandraWrapper.cc
 @brief   A wrapper that provides access to the pomdp read in by
          Tony Cassandra's file reading code, without requiring you
          to (1) directly reference global variables or (2) include
          all of the headers like sparse-matrix.h.  Also uses notation
          I am more familiar with.
