Position-Based CMFE Function: ``pos_cmfe()`` : ``pos_cmfe(<Donor Variable>,<Target Mesh>,<Fill>)``
The ``pos_cmfe()`` function performs the mapping assuming the two meshes,
that is the ``<Target Mesh>`` and the mesh upon which the

function is *optimized* to perform the mapping when the two meshes are also
*topologically identical*. In other words, their *coordinate* **and**
*connectivity* arrays are 1:1. In this case, the mapping can be performed
