[pyspark] adding disjunction and difference functions for rdds
I was looking for a way to perform disjunction and difference operations,
in other words:
* disjunction: find all elements NOT in A and B
* difference: find all elements in A but NOT in B
If there are better names for these functions, I'd be happy to change them.
I am a pyspark user so they are only in the python code. I would love having
them in Scala and Java too.
