"methods to generate random double RDDs or vector RDDs": should we mention that a user can extend RandomDataGenerator and generate a random RDD of whatever custom object they want?

I marked RandomDataGenerator as a developer API and didn't mention it in the guide.

Though we don't use default argument for methods in RandomRDDs, it is still not easy for Java users to use because the output type is either `RDD[Double]` or `RDD[Vector]`. Java users should expect `JavaDoubleRDD` and `JavaRDD[Vector]`, respectively. We should create dedicated methods for Java users, and allow default arguments in Scala methods in RandomRDDs, to make life easier for both Java and Scala users. This PR also contains documentation for random data generation. brkyvz Author: Xiangrui Meng <meng@databricks.com> Closes #2041 from mengxr/stat-doc and squashes the following commits: fc5eedf [Xiangrui Meng] add missing comma ffde810 [Xiangrui Meng] address comments aef6d07 [Xiangrui Meng] add doc for random data generation b99d94b [Xiangrui Meng] add java-friendly methods to RandomRDDs (cherry picked from commit 825d4fe) Signed-off-by: Xiangrui Meng <meng@databricks.com>
