Directional Light Falloff 1.0.5 for Maya (maya script)

Directional Light Falloff, adds the ability to add falloff to the standard directional light. When run, two new attributes under the light's shape node in the channel box will show up. One controls the light intensity, while the other controls the falloff distance.

This was inspired by the falloff network shown in "Advanced Maya Texturing and Lighting".
