Changes: added int *num_ghost == to keep track of the ghost layers
int ghlocal size == local size when ghosts are included
and the macros to access these variables
Files = struct_mv.h struct_grid.h
Reason = to keep track of ghosts and the ghost local size of the struct grid
Module: struct_mv
Data Structure/Function A
Changes: added prototypes to the new functions
Reason:
Files: struct_mv.h
