Changeset 27400 for trunk/psModules/src/imcombine/pmStack.h

Message:

Adding exposure map (both exposure time and number of inputs) to the outputs of ppStack. These are calculated both for the regular (convolved) and unconvolved stacks. These should compress pretty well, but I haven't enabled the compression yet. I also plan to add a weighted exposure time output.
