GetData and SetParams work. I'm understanding some of the rest.

-I commented out the pyfits import; it seems to be working.
-I commented out your getData function and used a test file with a diagonal line.
-As it was, setParams worked fine. I haven't done anything to it but comment on variables.
-I see circ-kern, which is our cookie cutter.
-I am confused by why/how we weight the umask data before turning it into bindata.
