This module has now been replaced by Matter.Composite.

All usage should be migrated to the equivalent functions found on Matter.Composite. For example World.add(world, body) now becomes Composite.add(world, body).

The property world.gravity has been moved to engine.gravity.

For back-compatibility purposes this module will remain as a direct alias to Matter.Composite in the short term during migration. Eventually this alias module will be marked as deprecated and then later removed in a future release.
