This tests the mask.py module. Since this
module is still in developement, so too are
these unit tests.
First test the red_maskgals() and gen_maskgals() functions.
Note: the gen_maskgals() function isn't written yet, so it
can't be tested. TODO
Next create a HPMask, check that it has maskgals and then
test to see if nside, offset, and npix are
the values that we expect them to be. These are
variables that tell us about how healpix is formatted.
Next test the fracgood array and its features, including
the fracgood_float and various fracgood entries.
Next test the compute_radmask() function which
finds if an array of (RA,DEC) pairs are in or out
of the mask. TODO
