Credit Analytics Regression Framework

Need to create the full regression frame work for curve analytics, with the following components:
 - Regression Scenario Container: Contains place holders for the full set of implementations of the curve analytics regression, along with base-lined tolerance checks
- Curve Regressors: Implementation of specific, elaborate functional regressions for each of the curve analytic objects.
 - Regression output suite: Storing the results of the regression - the time stamps, elapsed time, regression success/failure, and other regression details.
