(i) Added warning to dwa about deprecation; (ii) same T in tutorial1b as in parm1b; (iii) remove vistrails; (iv) remove tutorial 3 from website later as non-exisitent here; (v) change parameters in tutorial 2 so that it runs faster and gives a similar output as intended previously. I contacted Tama Ma and the conclusion was that time of flight should be removed from the tutorials instantly
