Improve efficiency of load balancing of a Frame, by working on a chunk at a time.
Dumb implementation of matrix transpose. Restrict operations only to matrices without factors due to mismatched domain issues.
Fix displayed time for multi-node operation: make member non-transient.
Fix link to build a new model.
Fix cancellation link redirection.

refactor all to use shared code for comparing with scipy/numpy quantiles..if numpy/scipy not installed, just compare with the sort algo (which is also done if numpy/scipy compares are done). Different tolerances for approx/exact/summary2 results

Fix rebalancing code and improve naming for chunk accessors.

Make proper API by hiding uninterested methods.
Minor polishement in DRF API.
Model API now provides number of input features.
Added GBM variable importance.

- variable importance is based on formula from
Friedman paper: Greedy Function Approximation: A Gradient boosting
machine

- it is computed as empirical improvement in squared error

- by default it is reported scaled with respect to the most
important variable
test stuff
Fix sanity checking during checkpoint restart.

Enable force_rebalance by default, for faster speeds out of the box for small
datasets.  For large datasets, nothing happens.  Fix NPE.
