IMWCS Using Pre-matched stars and the USNO-A2.0 Catalog in Verbose Mode

Run imwua2 (imwcs -c ua2), in verbose mode with a file of SExtracted image stars and a file of RA,Dec-matched stars, erasing all WCS information in the image before starting. This leaves the RA, DEC, EPOCH, and SECPIX keywords in place, however.
