Detailed Description

Algorithm to handle the eta hough transform.

This algorithm is responsible for the initial eta hough transform from space-points created in an upstream alg. It will write HoughMaxima into the event store for downstream use.

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
