Detailed Description

A wrapper class to reverse any ramp function such that the result starts from 1 decreasing to 0 from start over the duration and remaining at 0 thereafter.

Usage for scaling a vector:

    <name>
    {
        scale
        {
            type        reverseRamp;

            ramp        linearRamp;

            start       0;
            duration    10;
        }

        value
        {
            type        sine;

            frequency   10;
            amplitude   1;
            scale       (1 0.1 0);
            level       (10 1 0);
        }
    }
