Add a regression test script based on the python unittest framework. It looks for known files, runs 'jbig2dec --hash' and compares the result to the known correct value. Currently it looks for the ubc test files in '../ubc/' git-svn-id: http://svn.ghostscript.com/jbig2dec/trunk@143 ded80894-8fb9-0310-811b-c03f3676ab4d
