+This routine tests many Astrometry functions:
+    psChipInFPA()
+    psCellInFPA()
+    psCoordFPAToChip()
+    psCoordChipToCell()
+This routine loops through all valid cell coordinates and maintains a running
+set of (x,y) coordinates in the FPA plane.  It calls the first two functions
+with each FPA coordinate and determines the chip/cell that that coordinate
+corresponds to.  It then calls the last two functions to determine the actual
+chip and cell coordinates.  The cell coordinate is verified for correctness.
+ 
+It then calls
+    psCoordCellToChip()
+to determine if the chip coordinates that were generated agree with the chip
+coords returned above.
+ 
+Then, it calls 
+    psCellInChip()
+and flags an ERROR if the cell it returns is different from that of
+psCellInFPA().
+ 
+Then, it calls
+    psCoordChipToFPA
+to determine if the FPA coordinates are correct.
