 /**

  * This node cannot be dragged and manipulated in the same way as other

  * FigNodes in ArgoUML. It is actually an optional child fig (or more precisely

  * a path item) of a FigEdgeModelElement.

  * This allows the dashed edge of an association class to connect the

  * association edge and allows the dashed edge of a comment edge to attach a

  * comment to some other edge type.

  * GEF can only attach edges to nodes, by making this fig both a node and

  * containing it as a child of an edge we push the rules to allow edge to edge

  * connections.

  * TODO: We are inheriting a lot of functionality here that we don't really

  * require. We should attempt to make FigEdgePort extend FigNode.
