Matter.Composite module contains methods for creating and manipulating composite bodies.
A composite body is a collection of
Matter.Constraint and other
Matter.Composite, therefore composites form a tree structure.
It is important to use the functions in this module to modify composites, rather than directly modifying their properties.
Note that the
Matter.World object is also a type of
Matter.Composite and as such all composite methods here can also operate on a
