Algorithm

Read in parameters
Create input and output filenames based on parameters chosen.
Loop through prefixes for each directory in dirfile:
 if (withmask or withcheese) then
  Apply a mask or cheese mask if selected to eliminate point sources.
 endif 
 Apply PN OOT if necessary (but not for cheese maps)
 Accumulate a total outImage
 Calculate pixel bins to place incoming counts based on WCS coords.
End Loops
Write output mosaicked image to FITS and write new WCS keywords.
