    @andrewpalumbo thanks for the review!
    
    Fixed typos per your request and updated to convert to sparse vectors in 
cases where original vector was sparse. 
    
    re: the implicit conversion of the mahoutCtx, that threw errors so I left 
it as was.

> Currently the method for ingesting RDDs to DRM is `drmWrap`.  This is a 
> flexible method, however there are many cases when the RDD to be wrapped is 
> either RDD[org.apache.spark.mllib.lingalg.Vector], 
> RDD[org.apache.spark.mllib.regression.LabeledPoint], or DataFrame[Row] (as is 
> the case when working with SparkML.  It makes sense to create convenience 
> methods for converting these types to DRM.
