ENH: Added new LimitRange Function1 wrapper

Function1 wrapper that limits the input range of another Function1

Example usage for limiting a polynomial:

    limitedPolyTest        limitRange;
    limitedPolyTestCoeffs
    {
        min         0.4;
        max         1.4;

        value       polynomial
        (
            (5 1)
            (-2 2)
            (-2 3)
            (1 4)
        );
    }

Here the return value will be:
- poly(0.4) for x <= 0.4;
- poly(1.4) for x >= 1.4; and
- poly(x) for 0.4 < x < 1.4.
