Bind the values of a point with another point. Provide a relative offset object.

coupling = new Coupling()
coupling.couple(a, b, { x: 10, y: 10})

Both points are reative to their coupled position:

// Dragging either point will result in constant coupling.
dragging.add(a, b)

    Couple two points, binding the x,y,radius,rotation Apply a relative offset to update the values between binding changes when a side is manipulated, the _other_ side is updated. If B is the altered value, the relativeOffset is applied inversly. Apply a function to the relative offset key to capture live change.s

      Perform a single step of the coupling test, if either side of the connection has changed, bubble the update to its sibling - through the relative conversion.

      )
      from class_name
      dict_keys(['kind', 'word', 'static', 'computed', 'is_symbol', 'value', 'type', 'comments', 'pos'])

      Given an object and its cache, test each key in the cache and return a Set of changed keys

              hasChanged({foo: 20, bar: 10}, {foo: 10, bar: 10})
        ['foo']

    The return keys are values that do not match _a_.
    If the cache is flagged _dirty_, all keys are returned.

        hasChanged({foo: 20, bar:10}, {foo: 20, bar: 10, dirty: true})
        ['foo', 'bar']

    If no changes are detected `undefined` is returned.

            // is not called.
