Modifications made to BEMT as it was updating phi and thus AOA (at t_n+1)  which was then passed as input to UA. Therefore UA was using a premature input (t_n+1) instead of t_n. Also moved some code around as Greg figured it was not producing any other useful data but just auxiliary stuff for UA, so I moved it to the UA portion. This solves the issues of discrepancies between UA standalone and AD15.
