Feature Enhancements

Created a new status of Queued to represent the time a job is kicked off to the time it starts running. The Queued status will represent jobs that are submitted but have not been picked up by a worker yet. The Running status will represent jobs that are currently active.
The field "dataSet" has been changed from Required to Optional in the Create Filter service
Added the capability to upload a csv/gz file for users that have only a PostgreSQL database.
Added ROC curves as a comparison metric within the Prediction Model section to determine how sets of learners are compared. Available choices are now PEARSONS, RMSE, and ROC (only to be used with Boolean goals).
Updated error messages for file upload process to provide more detail
Added a new set of prediction_evaluation endpoints ( /datasets/:dataset_name/predictive_evaluation) which will run in addition to Predictive Scoring to calculate how well the scoring job ran given a filled goal column.

Corrected an issue where some services used exclusions and other used exclusionList. All services will use Exclusions, but ExclusionList is available for backward compatibility.
Corrected an issue where the incorrect http status code was returned when posting duplicate data sets. Posting a duplicate dataset will now return a 400 http status message.
Corrected an issue where a Failed message was returned when making a status call for a resultID that does not exist.
Corrected an issue where Elite Average incorrectly validates training and validation datasets in prediction model generation.
Corrected an issue where ordinals were being denormalized twice within Profiles.
Corrected an issue where deleting a dataset or dataset data did not remove the content of all associated tables.
