Work in progress towards PUB-603.
Use invoke() instead of execImpl().
Add support for visualization for DeepLearning neuron layers.  Might not work on Java7.
Merge branch 'master' into arno-deeplearning2
Restrict binary operations involving H2OParsedData objects to scalar numeric and logical R values only
Fix some typos in getting GBM prediction with H2O data
GBM Regression & Bernoulli add initial prediction

Model was built fine, but the scoring failed to add back the initial
prediction - so e.g. for regression the prediction was off by the mean.
Get crazy on checking the regression results

...also turn back on all the other GBM tests
Allow more bins in the top-levels of DRF & GBM

As the levels get deep & bin-counts become costly, shrink bins used to
the user-limit.  Cleanup leaked keys & IdeaJ warnings in GBMTest.
Golden DRF tests uniformly better.
No trailing file-sep on windows dirs

A good chance this is not needed on linux/mac either.
Fix adding mean to generated prediction code
OS-independent path sep in R test
Comment out redundant h2o.init() in R unit
Test of Bernoulli GBM predictions matches R within 95 percent confidence when bag.fraction = 1 in R GBM to match H2O behavior
Merge branch 'master' of https://github.com/0xdata/h2o
Slight speed optimization for typeahead keys
Merge branch 'master' of github.com:0xdata/h2o
Remove cyclic dependency of water and hex.
Added getProcessRss().
Add MemoryWatchdogThread and -mem_watchdog option.
Useful for memory leak hunting.
