adding hierarchy reading from text file
Changed prior API for getDelta, added more heirarchy support
Added functionality to hierarchical (normal) prior, compiles and runs, unit tested HierarchyReader and hierarchy representation in hierarchicalPrior.  TODO: Unit test getDelta
Unit testing API change
Unit tested the hierarchy functionality vs. the old hierarchy system
Turning on double precision
added hierarchical grid search
Added beginning framework for autosearch in two dimensions, TODO: stop when both dimensions are finished.
AutoSearchCrossValidationDriver now stops when both hyperparameters are finished, need to consolidate code +/- change API
Post testing of grid search and auto search for cross validation
Moving to two separate drives in autosearch, one for hierarchy, one for non-hierarchy
Reverting to old drive code for accuracy
Decomposed autosearch cross validation, implemented hierarchical cross validation in this setting, tested and validated compared to the old code
Moved Hierarchy cross validation to separate classes
cleaning up as necessary
Better handling of Hierarchy in prior classes, removed unnecessary code
Merging branch with hierarchical prior code into the master branch
