'Twigs' - branch's added to the existing, made from blending existing branches into new ones.
Some user settings for scale, orientation randomness, number of twigs and recursive twigs.
Tree From Curve,
- report error when nurbs or poly curves are used.
- don't throw errors when >4 branch's per segment are used. also try deal with this better. though no nice solution exists.
- default speed is 10x slower then before.
Was converting into a mesh and then doing location checks, to figure out what the radius should be and then interpolating. this was the slowest part of the script and it made a mesh every time.
Now use blenders bezier interpolation function and calculate points like blender does.
fixed a driver syntax error for the Z axis (typo)
