Function1 is an abstract base-class of run-time selectable unary functions which may be composed of other Function1's allowing the user to specify complex functions of a single scalar variable, e.g. time. The implementations need not be a simple or continuous functions; interpolated tables and polynomials are also supported. In fact form of mapping between a single scalar input and a single primitive type output is supportable. The primary application of Function1 is in time-varying boundary conditions, it also used for other functions of time, e.g. injected mass is spray simulations but is not limited to functions of time.
