tony d2156b5649 Updates. Includes property tree additions and fixes. Also Jon's first cut at 
multi-fdm capability.  Thanks also to Erik for pointing out a couple of typos.

FUNCTIONAL DESCRIPTION
--------------------------------------------------------------------------------
The purpose of this class is to take a set of initial conditions and provide
a kinematically consistent set of body axis velocity components, euler
angles, and altitude. This class does not attempt to trim the model i.e.
the sim will most likely start in a very dynamic state (unless, of course,
you have chosen your IC's wisely) even after setting it up with this class.

// 8: When this value is set, various runtime state variables
