Object sharing and service sharing across Oort nodes has been implemented.
Class OortObject, along with OortLong, OortMap and OortList allow applications to seamlessly share entities across nodes.
Class OortService and OortMasterService provide applications service forwarding functionalities, where an action started by a node is forwarded to another node for execution, and a result/failure is returned to the starting node.
Class OortMasterLong provides an atomic (across the cluster) shared counter that can be used to generate unique IDs.
