generator objects

[pasbi]

Add more generator objects (Cloner and Instance are examples for already existing generator objects) A generator hides its children and generates a new object.

• deform (add a custom offset to each point)
• outline
• subdivide (add intermediate points)
• ...

[pasbi]

though the cloner generator is very flexible, its usage is often cumbersome and not intuitive. Hence, add

• circular cloner (clone along circle with user-defined radius, phase, count)
• linear cloner (clone along line (1D, 2D) with user-defined step and count)
• path cloner (clone along path with user-defined start-, end-offset, count)
