experimenting with adding an object layer on top of the json response layer, so tests don't look into the json objects directly..get rid of functions I had to do some of that..make richer objects. saves typing, hides some amount of json api changes more from tests, easier porting of h2o tests to h2o dev
I may have broke some tests. will fix soon. (and move existing python h2o-dev tests to get rid of the infoFrom* functions to these classes for parse/inspect/summary response management/checking. (i bake in some assertion checking there too...passing 'expected' results (conditional) to this object layer.
