Combines with jquery-ui-draggable 1.9.2+ and jquery-collision 1.0.2+. Provides collision events while dragging, and handles collision-avoidance. Collision and containment settings are hierarchical and extensible, allowing for complex interactions.
Provides events for collision-detection during dragging
Just as with jquery-collision, can provide protrusion events as well (escape from a restraint)
Can prevent collisions of the draggable and obstacles
Can prevent protrusions of the draggable from multiple restraints
Can make selected children of the draggable the "colliding entities", allowing a draggable that is a bucket of other objects, where those child objects are the ones that collide with or avoid obstacles
Can be configured to have multiple classes of obstacles and restraints under the same draggable
