World Objects

A set of world objects:

•   World Trigger is a cuboid shaped object, which fires callbacks when any node (collider or not) gets inside or outside of it.
•   World Clutter is used to manage a great number of node references, baked as one object. Objects are scattered, scaled and oriented randomly, they cannot be managed manually.
•   Switcher is a cuboid shaped object, switching off (or turning on) all of the nodes inside of it immediately. A world switcher should be a parent node for the nodes it controls.
•   Occluder is an object used to cull objects that are not seen behind it.
•   Transform is is a succession of transformations based on an arbitrary path.
•   World Expression is a cuboid shaped object, inside of which arbitrary expressions are executed. These expressions can be executed for world expression children nodes as well.
•   World Spline Graph is used to place various nodes at points and along the segments (linear or curved) of a spline graph. It can be utilized to create roads, pipelines, etc.
