In <b><i>spatial_v1</i></b>, there were separate functions for spatial and
planar arithmetic.&nbsp; For example, <b>crfp</b> was the planar version
of <b>crf</b>, and <b>IDp</b> was the planar version of <b>ID</b>.&nbsp;
In <b><i>spatial_v2</i></b>, the planar functions no longer exist, and the
spatial functions now implement both spatial and planar arithmetic.&nbsp;
Also, the planar version
