start of a parser-exception test
WIP for catching parser exceptions & doing cleanup

MRTask single-thread mode does not use a H2OCallback, just compute left
& rite in-thread.

Remove H2OCallback catching all exceptions & printing.
Just take the default exceptional completion.
Capture exceptions in DTask.
Closer... now cleaning up all but the partial new chunks

not tried multi-node yet...
Cleanup single-node parser crash

or at least tossing NPE when reading a Chunk, on single-node - cleans
up.  Move testing own file.  Known to not-work multi-node.
Fix parser-test multinode

Also fix bug in SummaryTeast

Fix path of weather.csv
Fix for PUB-166. Forgot to capitalize Gamma to get correct link function in .h2o.__getFamily method

Fix for PUB-671. Stop with an error when user tries to select non-existent column in an H2O dataset.
Added validation dataset for smalldata Arcene and Gisette
Reformat Gisette dataset
modify logging for number of chunks to load
variable importance support for bites of DIVotes
Add NOPASS test where underfitting occurs
send an R expression without H2OParsedData objects to h2o
