Add implementations of parallelPrefix() in Arrays for Object, int, long, 
and double arrays.


This work was done over in the lambda forest mainly by Doug Lea, with 
some small spec updates by myself.

Note: Some work still need to be done to clean up the test, but I would 
like to focus mainly on the API and try to get it finalized first.
