fix in CHANGELOG.
1024M for Hadoop testing. May not be enough still. Need to figure out how to make a new JVM for each @Test.
Work on making the toString() of Traverals pretty. Simplified the toString() impls by having a smart TraversalHelper.stepString().
ElementFunctionComparator and ElementValueComparator now exist to allow for vendor introspection into comparator contructs involving elements -- e.g. order(). @mbroecheler  Likewise ElementValueFunction exists for vendor introspection -- e.g. aggregate(), group(), groupBy(), etc. More work on toString() look-and-feel of steps and traverals. CoinStep is now bulk-aware (though I bet there is a more efficient algorithm).
renamed FunctionAcceptor to FunctionConsumer, Comparing to ComparatorSupplier, and ComparatorAcceptor to ComparatorConsumer. Naming consitency with Java8.
dah. now its FunctionHolder and ComparatorHolder. Simple, clean.
dah.
my last 2 pushes were bad. getting hasty. sorry.
renamed ComparingRemovalStrategy to ComparatorHolderRemovalStrategy to be consistent with new interface name.
Graph.System is now Graph.Hidden with the vendor namespace being ~ (like hidden in the past). Updated docs with a note about namespaces. Fixed #399. Fixed #240.
