Reference object

A global  object is a new type of INtime object. It contains information about an object residing on another node: the location of the node and the RTHANDLE of the object in the node.
Once a reference object has been created, its RTHANDLE can be used wherever an RTHANDLE of that object type can be used.
Note that it is allowed to create a reference object for an INtime object residing  on the same node.
