MAHOUT-1838: Simple 2d plotting of a sampled DRM
This is a bare-bones beginning to some mahout plots. Takes a `DRM` and
creates a scatter plot of a sample of the first two columns.
Tested in the shell and works when the sample size is hard coded. But am
currently having some problems with the simple calculation of the sample
percent- simple fix I'm sure..

> Add basic 2d and 3d plotting capabilities to Mahout using the Smile library:
> https://github.com/haifengl/smile
> I've prototyped an {{mplot2d}} class here to sample a certain percentage of a
> DRM's data using {{drmSampleKRows()}} and to create a 2d plot from the
> resulting x,y coordinate matrix, and tested from the spark-shell as a POC.
> Extending to 3d should be trivial:
> The Smile-Plot library has some very nice plotting features, all of which can
> easily integrated into mahout:
