public class MoveElementsCommand
Command to move model elements using the EMF action protocol.
If the target features are not specified in the request, and the features fomerly containing the moved elements exists in the target element, they will be used.

Looks for the feature first in the elements map. If none is specified, tries to use the same feature that contained the element in its old location. If the old containment feature doesn't exist in the new target, uses the MSL utility to find the first feature in the target that can contain the element being moved.
