+Recall object operator
+
+Generic functions to re-create an object that was created
+with a "Add Mesh" operator.
+
+The "Add Mesh" operator has to store the "recall" information
+in the object properties for this to work.
+
+Usage:
+
+Select an "recall enabled" object and click the "Edit" button
+in the "recall" apnel of the Tool Shelf.
+
+Known issues:
+
+The recall doesn't take the rotation/scaling of the
+exiting object into account.
+i.e. The new object will be created as if it's created
+manually at the location of the exiting object.
+This also means that "align to view" may affect
+rotation of the new object.
