+
+  I have changed addstar to use the new, more flexible, SkyRegion
+  concept to define the sky layout rather than just the GSCRegion
+  files.  This includes the ability to subdivide the existing
+  GSCRegion concept, and to have a more flexible sky table
+  arrangement.  
+
+  Names of catalog files are a bit tricky.  The SkyRegion functions
+  return base names without fullpath or extensions (ie, n0000/0012).
+  There are a few places in addstar which need the fullname:
+
+  SkyListExitingSubset () requires the path and adds .cpt
+
+  load_pt_catalog () takes the path and adds .cpt.  it also allocates
+  a filename entry for catalog, which is freed later in the loop in
+  addstars
+
+  mkcatalog uses the name in the catalog structure and replaces .cpt
+  with .cpm, .cpn, .cps as needed.
+
+
