Matei Zaharia 22b8fcf632 Added fold() and aggregate() operations that reuse an object to

for each element merged. Fixes #95.

Matei Zaharia d12122502b Various improvements to Kryo serializer: 
- Replaced modified Kryo version with the standard one augmented with
  the kryo-serializers package, which includes support for classes with
  no-arg constructors (that was why we had a modified Kryo before)
- The kryo-serializers version also fixes issue #72.
- Added a bunch of tests.
- Serialize maps and a few other common types properly by default.

Matei Zaharia 4db50e26c7 Fixed unit tests by making them clean up the SparkContext after use and 
thus clean up the various singletons (RDDCache, MapOutputTracker, etc).
This isn't perfect yet (ideally we shouldn't use singleton objects at
all) but we can fix that later.
