Upgrade of graphs to Matplotlib 1.5.0

[finmod]

In the recent upgrade of Matplotlib from 1.4.3 to 1.5.0 introduced in Anaconda3 2.4.0 (python 3.5), there are quite few modifications in the style of designing graphs. The following error appears in the lakemodel example and in a few other examples and solutions:

@finmod Thank you for the report. I reproduced the error.

It seems

pd.set_option('display.mpl_style', 'default') # Make the graphs a bit prettier

on line 14 conflicts with Matplotlib 1.5.0. As a quick fix, commenting out this line should make the code work.

@finmod Thanks for letting us know. We're going to upgrade everything to Python 3.5 and latest versions of the libraries over the next few weeks.

Thanks @finmod. This has now been fixed and the code in quantecon.applications repo updated.
