Hey Xiangrui, can you also add Scaladocs on the main methods? Otherwise it
looks weird to have an experimental method. Really these were meant to give
people an easy way to run these algorithms from the command line, but very few
are probably using it because we didn't document it, so we could also move
these methods into examples instead (e.g. in an org.apache.spark.examples.mllib
package in the examples project). They are also useful for perf testing during
development.
