Detailed Description

Abstract class state variable.

   Simple exponential system class header implementing a state variable:
   @code
   class RateGrowth
   {
   public:
       real rate;
       virtual real Derivate(const cmf::math::Time& time) {return rate*get_state();}
   };
   @endcode

Public Member Functions
	StateVariable (real InitialState=0, real scale=1)
	ctor
virtual real	dxdt (const cmf::math::Time &time)=0
	Returns the derivate of the state variable at time time.
real	get_state () const
	Returns the current state of the variable.
void	set_state (real newState)
	Gives access to the state variable.

Protected Member Functions
void	MarkStateChangeHandled ()
	Sets the updated flag (m_StateIsNew) to false.
bool	StateIsChanged ()
	Returns if the state was currently updated.
