     3= Assumptions about the universe =
     4It might be necessary to extend SymbolicUniverseIF with a RealUniverseIF.  For accuracy, it is necessary for some assumptions to hold that are not necessarily true in an arbitrary symbolic universe.
     5 * Associativity.  We need to know that ''f(h) + (f'(h) + f"(h)) = (f(h) + f'(h)) + f"(h)''.
     6 * Commutativity. We need to know that ''f(i*h)=f(h*i)''.
     7 * No over/underflow.
     8 * Arbitrarily precision.

    410 * ModelBuilder must be updated to deal with abstract functions, derivatives
