Update README.md

<b>The Code</b>
--------------------------
The code to demonstrate the example is crude. I copied some of the code from examples on their <a href="http://matplotlib.org/>website</a> and hard-coded paths to reference my data. The data is able to be rendered but at this point can't make exact sense of it. More work needs to be done.

<b>Next Steps</b>
--------------------------
Using this library relies heavily on the numpy library which I did not foresee when I dove into this. Going forward...

* Choose a bigger sample of data and choose the best method to plot it
* Keep plugging away at this
