Detailed Description

Implements heuristic, seed-based, space-efficient interaction prediction based on minimizing ensemble free energy of interaction sites.

Note, for each seed start (i1,i2) only the mfe seed is considered for the overall interaction computation instead of considering all possible seeds starting at (i1,i2).

Constructs a predictor and stores the energy and output handler

Parameters

energy	the interaction energy handler
output	the output handler to report mfe interactions to
predTracker	the prediction tracker to be used or NULL if no tracking is to be done; if non-NULL, the tracker gets deleted on this->destruction.
