!> SUBROUTINE: PARMEXCH - ?????
!> PROGRAMMER: JIM TUCCILLO
!> ORG: ?????
!> DATE: 01-02-??
!>
!> ABSTRACT:
!> IBUFEXCH IS THE SIZE OF THE EXCHANGE BUFFERS USED FOR THE HALO EXCHANGES. 
!> THE CURRENT SIZE SHOULD BE MORE THAN SUFFICIENT FOR THE FORSEEABLE FUTURE.
!>
!> IBUFEXCH WOULD NEED TO BE INCREASED IF YOU EVER RECEIVE AN ERROR FROM THE MPI LIBRARY INDICATING
!> THAT THE RECIEIVE BUFFER IS TOO SMALL. 
!> YOU SHOULD DO A "MAKE CLEAN" IF YOU INCREASE IBUFEXCH.
