  corSpatial is a virtual class: the real classes
derived from it (corGaus, corLin, corSpher, corExp)
are listed.

  I suppose there would be some argument for adding
corSpatial to the "see also" list -- although it is
listed on each of the specific pages for the four
real spatial classes, so you would certainly get there
if you were poking around in the documentation.
