+# Pan-STARRS uses a 64-bit detection ID.  keep this in two 32 bit ints
+# for C89 compatibility.  The objID is constructed based on the
+# position of first instatiation.  this is actually quite expensive
+# because we need to include the uniqueness test to construct this,
+# which requires a select for each new object.  Therefore, I will use
+# a table based ID (table ID + object ID), and we will have to
+# re-number the object IDs if we change the table density, OR treat
+# all subdivisions as entries which are from a foreign table.
