Generalized linear classification model.
Calls h2o::h2o.glm() from package h2o with family always set to "binomial".
H2O Connection
If no running H2O connection is found, the learner will automatically start a local H2O server
on 127.0.0.1 via h2o::h2o.init().
If you want to connect to a remote H2O cluster, call h2o::h2o.init() with the appropriate
arguments before training or predicting.
