Timothy Hunter 2ecbe02d5b [SPARK-12212][ML][DOC] Clarifies the difference between spark.ml, spark.mllib and mllib in the documentation. 
Replaces a number of occurences of `MLlib` in the documentation that were meant to refer to the `spark.mllib` package instead. It should clarify for new users the difference between `spark.mllib` (the package) and MLlib (the umbrella project for ML in spark).

It also removes some files that I forgot to delete with #10207

Author: Timothy Hunter <timhunter@databricks.com>

Closes #10234 from thunterdb/12212.

Optimization of linear methods

The optimization algorithm underlying the implementation is called Orthant-Wise Limited-memory QuasiNewton (OWL-QN). It is an extension of L-BFGS that can effectively handle L1 regularization and elastic net.
