which I can only assume is due to the new way ascii handles tables.

I created this method to use as a replacement for unumpy.uarray that handles
the tables created with astropy.io.ascii.

Usage is the same as uncertainties.unumpy.uarray.

:type x,errx: arrays created with astropy.io.ascii.
:returns: uncertainties array.
