This script is used to duplicate a source object over a curve evenly spacing the copies.
It uses motionPath nodes to achieve that. The resulting objects can be attached to the curve
by parenting the copies to locators constrained to the curve. Then Each locator has an "U Value"
attribute that lets you animate the object along the length of the curve. The copies can be made
regular duplicates or instances.

     Some parameteres of the resulting motionPaths can be adjusted (world up type (Scene Up/Normal),
inverse up, inverse front, front axis, up axis).

     The source object can be any transform: light, locator, nurb, mesh, curve,... anything with a transform node.

    - Now you can choose multiple curves to copy objects onto.


Any feedback appreciated.
