    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 default kryo serilizer mb to the spark-shell. problem calculating sample percent
in mplot2d- getting 0 back

> 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:
