AP - Package that allows you to plot simple graphs in ASCII, a la matplotlib.
============================================================================

This package is a inspired from Imri Goldberg's ASCII-Plotter 1.0 (https://pypi.python.org/pypi/ASCII-Plotter/1.0)

At a time I was enoyed by security not giving me direct access to my computer, and thus to quickly make figures from python, I looked at how I could make quick and dirty ASCII figures. But if I were to develop something, I wanted something that can be used with just python and possible standard-ish packages (numpy, scipy).

So I came up with this package after many iterations based of ASCII-plotter.  I added the feature to show multiple curves on one plot with different markers.  And I also made the usage, close to matplotlib, such that there is a plot, hist, hist2d and imshow functions.

TODO:
-----
* [ ] imshow does not plot axis yet.
* [ ] make a correct documentation
* [x] publish on github
