Title: Added incremental building of ensembles and fixed adaboost

Adaboost implementation had a bug which resulted in the D vector of dataset weights being incorrect and in some extreme cases leading to non-termination and infinity errors.

Ensembles now can have "steps" where they have a member added on to the existing ensemble. This only works for some ensemble techniques that can be expanded this way.
