Description

This task aims to consolidate and cleanup the scripts for stepwise linear regression and stepwise GLM as builtin functions.

• Create a new builtin function for stepGLM (the details can be copied from scripts/algorithms/StepGLM.dml)
• Refactor the stepLm and stepGLM functions to internally call lm and glm respectively (no code duplication)
• Devise a generic step-X function which allows passing second order functions of any regressor or classifier (via eval)
