added sparse hack for glm.
Added all 1-5 bedrooms rent data
Updated the way percentiles are computed. Now constant columns will get percentiles (with all the values being the constant value).
Merge branch 'glm_sparse_update' of github.com:0xdata/h2o into glm_sparse_update
minor code cleanup of the sparse glm update.
Sparse glm update bug fix. There was an NPE bug in case of non-gaussian family and gram getting NaNs/Imfs in the second iteration.
Parse glm update. Fixed bug when there is only one categorical column with 2 levels.
Sparse glm update. Had cholesky being solved in place, overwriting the gram, however, we need to keep the gram intact in case of non-spd matrix (in which case we add L2-regularization and try again).

Changed it to create a clone of the gram and perform in-place cholesky on the clone.
Just added few comments to sparse glm.
tiny bug fix. added missing call to cholesky in DLSM in case of non-SPD matrix and bumping up rho.
Update of the cholesky re-try with larger rho mechanism.
noticed 'beta_eps' param should be 'beta_epsilon'. Also updated some of the rand param choices to cover current range of choices for some of the newer params.

reduce to 1000 and 2000 multi-file parse, to see if ec2 will pass
when writing out a csv file (downloadCsv) h2o writes time data as the internal format number, rather than time like the source. that means the value_size_bytes and row_size will differ when re-parsing that csv (compared to to the original. Don't check.
since we remove the source key now after parse, if we're iterating re-parsing the source key, we also have to redo the import folder, to get the source key back in (used to import outside the loop).
use parseFile instead of import folder because dataset is in smalldata, and the import will be redirected to look in s3 bucket in ec2 (and it's not there). Add result checking (of kmeans after scoring) and iterations.
Added ParserTest ported to fluid vets + few bug fixes in fluid vets parsing to pass the test.

removed dog print from Frame.
