Bugs and Changes

-Fixed a problem in ITDSalienceLocalizer:  for unknown reasons the
middle of the phase-lag space was shifted two lags in the positive
direction.  Lags and angles are now computed properly and more
accurately.
-New: ComputeAngleUsingITDSalienceXcor() computes a dynamic
cross-correlation rather than a dynamic GCC-PHAT.  This seems more
accurate in complex auditory scenes.
