Title: Performance fixes on NetworkProjections + MDS/VQ stopping conditions

NetworkProjections performance improved with respect to data passing
(using member variables instead of passing arguments), stopping
conditions added to MDS and VQ to prevent unnecessary executing if
distortion/stress unchanged. Can epsilon and number of iterations
without change be modified in the code.
