virtual Standard_Integer GetStateNumber ()
 return the state of the function corresponding to the latestt
call of any methods associated to the function. This
function is called by each of the algorithms described
later which define the function Integer
Algorithm::StateNumber(). The algorithm has the
responsibility to call this function when it has found
a solution (i.e. a root or a minimum) and has to maintain
the association between the solution found and this
StateNumber.
Byu default, this method returns 0 (which means for the
algorithm: no state has been saved). It is the
responsibility of the programmer to decide if he needs
to save the current state of the function and to return
an Integer that allows retrieval of the state.
