Burak Yavuz 9e2ffb1328 [SPARK-7388] [SPARK-7383] wrapper for VectorAssembler in Python 
The wrapper required the implementation of the `ArrayParam`, because `Array[T]` is hard to obtain from Python. `ArrayParam` has an extra function called `wCast` which is an internal function to obtain `Array[T]` from `Seq[T]`
