Array between with dynamic preview

@Gijs wrote:

The script below allows you to make an array of curves or poly(surfaces) linearly. Where ArrayLinear will make an array where you set the distance between items, this script will distribute the arrayed objects over the distance you pick. Made this mainly for learning purposes, but might be useful for some. Should work on Windows and Mac.

"""
This script allows you array curves, surfaces and polysurfaces, from object
boundingbox center to a picked point, where the new objects will get distributed
between center and picked point. You will see a dynamic preview and can
change the amount while the preview updates.
