FMS-FPost alignment - for discussion with Akio (2)

- Updated FMS projection by adding rotation WRT FPost slat angle:
   x' = x * cos(theta) - y sin(theta)
   y' = x * sin(theta) + y cos(theta)
   where " theta = FPostSlatAngleOnDB - 90 ", x (y) = Projected FMS point's x (y)

- Updated plotting w/ Akio's scaling + Zoomed FPost plots in by using its X(Y) acceptance
   a. FPS: correlation highlighted
   b. FPost: cannot see correlation

- Plan to repeat once recent (Mar 15) muDSTs are available
