C U R V -e : Vine Growth RnD

One of the many features of my scripts C U R V -e and T U B -e .
C U R V -e creates curves realtime based on the positions of the particle for each frame (no having to cache the scene and read the particle positions from the file) . It allows you to "previs" the curves before you actually simulate them (even though it's a simple single button-click if you don't like the generated curves).
T U B -e creates nurbs tubes from the curves. Lots of parameters still need to be implemented to this one.

Some cool features:
1. the ability to create dynamic curves.
2. ability to taper all the tubes through the UI
3. ability to change the radius of all the tubes uniformly

What I'd like to do:
1. offset the growth animation for each "tube"
2. add the control for easily randomized scale for each "tube"
3. add collision parameter to the UI
(and probably quite a few more things I can't think of at the moment..)
