Add varients of Map, Reduce, etc. such that predicates are called on Goroutines.

Note: must document to not use cross-dependant predicates; cannnot use a predicate which is dependant on the completion of a prior running of the same predicate.

May want to do some work around List or ither collection type to ensure consistent API.
