initialize the partition transfer object

Warning: Input and output groups may have a different number of processes. In that case the transfer will only work if some further constraints are met (see sanity checks below). One of the cases where it should work is when one of the groups is a subgroup of a Cartesian topology created from the other group. This is the case when one of the groups is mpi_world, the other is the parallelization in domains group, and there are no slaves. If the optional argument inverse is set to .true., the direction of the transfer is inverse: part_out is assumed to specify the partition on the incoming mpi group. This is useful if one needs to get points defined on the output group.

Parameters

[in]	np	the number of local points in the input partition
[in]	global_index	the global indices of the points of the input partition
[in]	mpi_grp_in	mpi group of in_mesh
[in]	mpi_grp_out	mpi group of out_mesh
[in]	part_out	point -> partition
[out]	nsend	Total number of points to be sent
[out]	nrec	Total number of points to be received
