917	Add mechanism for IPP to know that a given file has already been detrended (from header or filename)	jester@…	Paul Price	"Sometimes (for processing of SDSS images, all the time), we want to inject images into IPP that are already flatfielded etc. I can make the PROCESSED reduction class the default in the camera.config, and/or I can update chipRun.reduction by hand after registering images in ippMonitor. But it would be useful for IPP to have a mechanism of recognizing automatically that a given image has already been detrended. This could be by specifying certain header fields, or in the SDSS case, the filename fpC*.fits tells you that the image is a reduced (""corrected"", hence C) image produced by the frames pipeline (hence fp)."	enhancement	reopened	high		ippScripts	unspecified	minor
