Error setting up the camera

Unable to find automatically generated camera configuration SDSS-SKYCELL-CHIP in site configuration.
-> psphotParseCamera (psphotParseCamera.c:34): Problem in configure files
Unable to generate new file from PSPHOT.INPUT
The psphot command-line executable (not the library version, I believe) does a chip mosaic on the input data before any photometry is performed --- it assumes that you're working with data straight from the camera (for which you want to deal with all cells on the chip together), rather than a skycell.
Fixed by telling the system (in psModules/src/camera/pmFPAfileDefine.c) that it doesn't have to make a chip-mosaicked camera out of the skycell camera. Also cleaned up the concepts that are set by default for skycell cameras. These changes allow the psphot command-line executable to run on the stacked (or warped or diffed) image.
