SPARK-1357 (addendum). More Experimental items in MLlib

Browse source 
Per discussion, this is my suggestion to make ALS Rating, ClassificationModel, RegressionModel experimental for now, to reserve the right to possibly change after 1.0. See what you think of this much.

Author: Sean Owen <sowen@cloudera.com>

Closes #372 from srowen/SPARK-1357Addendum and squashes the following commits:

17cf1ea [Sean Owen] Remove (another) blank line after ":: Experimental ::"
6800e4c [Sean Owen] Remove blank line after ":: Experimental ::"
b3a88d2 [Sean Owen] Make ALS Rating, ClassificationModel, RegressionModel experimental for now, to reserve the right to possibly change after 1.0
