Merge pull request #65 from tgravescs/fixYarn

Fix yarn build

Fix the yarn build after renaming StandAloneX to CoarseGrainedX from pull request 34.
Removed TaskSchedulerListener interface.

The interface was used only by the DAG scheduler (so it wasn't necessary
to define the additional interface), and the naming makes it very
confusing when reading the code (because "listener" was used
to describe the DAG scheduler, rather than SparkListeners, which
implement a nearly-identical interface but serve a different
function).
Rename SBT target to assemble-deps.

Removed unnecessary code, and added comment of memory-latency tradeoff.
Default blockSize is 4MB.
