DESCRIPTION
     This engine linearly interpolates between two floating-point values,
     based on the alpha input value. The alpha value should be between 0.0 and
     1.0.

     The input fields can have multiple values, allowing the engine to
     interpolate several objects in parallel. One of the inputs may have more
     values than the other. In that case, the last value of the shorter input
     will be repeated as necessary.

INPUTS
     SoMFFloat           input0
     SoMFFloat           input1
          The engine linearly interpolates from input0 to input1.
