changing tICA_train.py to use the new code in tICA.py
Merge branch 'tica_mle' of github.com:schwancr/msmbuilder into tica_mle
got everything working! msmbuilder.tICA.tICA now acts as a container for the tICA solutions, with a method called 'project' that will project a trajectory on to whichever tICs you want. Then there is a distance metric called RedDimPNorm which will use such an object to calculate distances. To make this more general, I may want to create an AbstractProjectionClass of which tICA is a subclass. this would be a blueprint for any other dimensionality reduction techniques (like LSDMap, ISOMAP, PCA, kernel-tICA, etc.)
