0.8.4, 2014-01-14 -- Changed the optimization in profilex scaling
                     to fit background, which added an extra fitting
                     parameter, but makes more sense.

0.8.3, 2014-01-10 -- Fixed bug where integration returned bin averages
                     instead of summation in averaging mode of profilex.

0.8.2, 2014-01-10 -- Forgot to change Pillow dependency back to PIL
                     on previous release.

0.8.1, 2014-01-10 -- Improvements to the summation part of the docs.
                     Fully documented the combine_reflections setting
                     of **powderx**. Renamed the bin_reflections
                     setting to combine_reflections.

0.8.0, 2014-01-10 -- Mostly just a documentation improvement and
                     a version bump to reflect the temperature
                     factor and Lp correction added yesterday.
                     Added mathjax support to docs.

0.7.2, 2014-01-09 -- Added documentation for the powder summation.
                     Also, the user now has control over isotropic
                     temperature factor and Lp correction in powderx.
                     Fixed behavior of profilex for scaling multiple
                     patterns.

0.7.1, 2014-01-08 -- Fixed some documentation.

0.7.0, 2014-01-08 -- Ready for pypi release.
                     Uitilities tested and functionalities
                     are consistent. Documented. Bam!

0.2.2, 2013-12-20 -- Initial release.
