Added configurable wind direction 

- Add option in simulation options. 0-360 wind direction.
- changed plot parameter names to Position East-West/North-South from Position parallel to wind/lateral
- added Ground Track plot type (Plots Position North-South against Position East-West with secondary altitude plot.

TODO
- Still need to work on wind model to allow some noise in the direction and direction shift with altitude.
- Need to find a way to make plot axes square for the Ground track plot.
- Maybe introduce a "3-D" plot of ground track
