[Jsbsim-matlab] Major Change in JSBSim

[Jon S. B. <jon...@co...>]

I have made this evening a major change in JSBSim. I have removed the
FGState class. This class had become mainly a holder of the simulation time,
the timestep size, and initialization functions. Those functions have been
moved to the executive, FGFDMExec. The interface class for FlightGear,
JSBSim.cxx, has been adjusted in JSBSim CVS.

For other simulations such as OpenEaagles and Outtera, the application that
calls JSBSim should be careful to make sure that the executive is used to
access the time functions.
