import/parse as VA, then switch h2o.beta_features and do GBM. use exec to change .gz colum to integer 0/1 for binomial classifer (GBM doesn't have case/case_mode like GLM?) ..run multifile gz (10), covtype.data and covtype20x.data
use jobs list to decide when parse and GBM are individually complete (no polling)
Merge branch 'master' of github.com:0xdata/h2o
