+// CLASS DESCRIPTION (MPxSpringNode)
+//
+// MPxSpringNode allows the creation and manipulation of dependency graph
+// nodes representing springs.  This is the top level of a hierarchy of
+// spring node function sets.  It permits manipulation of the attributes
+// common to all types of springs.
