constructor for a redistribution collection that is comprised of multiple other redistributions

Parameters

[in]	redists	redistributions
[in]	num_redists	number of redistributions
[in]	src_displacements	array of displacements of the source input arrays for the exchange
[in]	dst_displacements	array of displacements of the destination input arrays for the exchange
[in]	comm	MPI communicator

Remarks: all redistributions need to be based on the same MPI communicator
