Merge pull request #2 from theengineear/master

IPython notebook added for plotly and plotly_renderer reformatted.
Reformatted PlotlyRenderer in plotly_renderer to be a bit cleaner.

Dictionaries are more explicitly created to make them more readable/editable.
Changed renderer to include colors on lines (whoops) + examples.
Added test_plotly.py which contains functions for nose tests.

To test these in command line, 'cd' into 'tests' dir and type:

nosetests test_plotly.py

Everything should pass.
Changed axis numbering in PlotlyRenderer and added 'fixer-function'.

Plotly uses xaxis, xaxis2, xaxis3, etc. for axis ordering.
PlotlyRenderer now inherently uses xaxis1, xaxis2, xaxis3, etc., but
reverts things related to xaxis1, x1, y1, and yaxis1 back to standard
plotly words before calling plotly.
Merge branch 'nose' into renderer
