REF/TST: split up boxplot function into a calculator (cbook.boxplot_stats) and a drawer (axes.bxp).
Existing function now relies on these two functions.
BUG: fixed cbook tests for Python 2.6
ENH: allow for custom patch artist and labels to the boxplots
WIP: more tests and add option to toggle box

TST: added tests for all of bxp and more boxplot tests

TST: fixed boxplot baseline image

TST: added baseline images for bxp
DOC/REF: added docstring for axes.bxp and refactored all references to outliers as fliers
REF/TST: update boxplot_stats test with outliers changed to fliers

ENH/TST: boxplots stats now takes a labels kwarg

MNT: minor PEP8 whitespace fix
MNT: reran boilerplate.py
DOC: added blurb in changelog
MNT: got rid of build-breaking `u''` strings in pyplot
MNT: fixed changelog whitespace
ENH: cbook.boxplot_stats can now set the whiskers to -range- (min/max) or specified percentiles. If IQR is zero, min/max are used
TST: added tests and baseline images for new whisker behavior
ENH: added remaining bxp kwargs to boxplot
DOC: expanded boxplot_stats docstring
DOC: added examples
DOC: impoved example boxplot figure layout and confirmed that they build with docs
