mpi.cart.get provides the user with information on the Cartesian topology associated with a comm.

1	mpi.cart.get(comm=3, maxdims)

`comm`	Communicator with Cartesian structure
`maxdims`	length of vectors dims, periods, and coords in the calling program

The coords are as given for the rank of the calling process as shown.

mpi.cart.get returns a vector containing information on the Cartesian topology associated with comm. maxdims must be at least ndims as returned by mpi.cartdim.get.
