Parameters:
[in,out]MRecv{an already existing, but empty SpMat<...> object}
[in]essentials{carries essential information (i.e. required array sizes) about ARecv}
[in]arrwin{windows array of size equal to the number of built-in arrays in the SpMat data structure}
[in]ownind{processor index (within this processor row/column) of the owner of the matrix to be received}
Remarks:
{The communicator information is implicitly contained in the MPI::Win objects}
