axes.color_cycle is deprecated

[wcarthur]

c:\python27\lib\site-packages\matplotlib\__init__.py:878: 
UserWarning: axes.color_cycle is deprecated and replaced with axes.prop_cycle; 
please use the latter.

axes.color_cycle is used in PlotInterface.figures (line 244 and 303) and PlotInterface.timeseries (line 67 and 117)

This will necessitate a change to the minimum version of matplotlib

Now an attribute error.
