// .NAME Partition - Partition MPI processors into cartesian grid
//
// .SECTION Description
// Partition allows MPI to divide the number of processors it is given and
// to set the position of this processor within the Cartesian grid. Using
// that information with wraparound, all neighbors of a processor are
// also computed. This class is static and will be shared by all classes
// within the infrastructure.
