    This adds a Guava dependency and does some Hadoop profile magic. We have to be very careful
when merging this to be consistent with changes in #454 by @rmetzger 
    
    I think that #454 should significantly simplify the Hadoop profile and Guava business.

> This will be a method that implements the GAS computation model, but without the "scatter"
step. The phases can be mapped into the following steps inside a delta iteration:
> gather: a map on each < srcVertex, edge, trgVertex > that produces a partial value
> sum: a reduce that combines the partial values
> apply: join with vertex set to update the vertex values using the results of sum and
the previous state.
