Added explicit param_names to sklearn interface. This allows us to selectively ignore parameters.
Fixed bug in ParamInformation.distance (copy/pase error).
Added storing of dimensionality_per_param to grid; added support for objective function arguments; fixed error where only the first grid_point is returned.
Added scikit learn estimator evaluation and grid evaluation to testEvaluationFramework.
