A new function, interpretDQvalue, has been added to 'pytools.fileutil' to provide a way to get all the power-of-2 integer values that were summed together (as DQ array values) to generate a given integer value. This addresses help call 779423 from INS.  In addition, the module was modified to import numpy as np instead of N.  WJH
