Conformal predictive systems (simple)

This demo describes how to enrich the regression workflow with conformal prediction methods that allows to estimate model prediction certainity and control the desired error rate. The workflow is also implemented with Integrated deployment extension, so it automatically creates production code. Conformal prediction is agnostic to prediction algorithm, so users can easily replace it with any other classification algorithm.
