    Inputs:     ContextNode: Pointer to a node which this node is to be attached to.
                MonoOn Direction: MonoOff
                Specifies the direction in which the node is to be attached to the
                ContextNode. The values this variable can take are as follows:
                                  
                PREV      : Attach node as a previous sibling of the context node
                NEXT      : Attach node as a next sibling of the context node
                FIRSTCHILD: Attach node as the first child of the context node
                LASTCHILD : Attach node as a last child of the context node

                BoundingRect: Bounding rectangle

                The remaining inputs specify the status of the node:
            
                Locked:     Is node locked ?
                Mangled:    Is node mangled ?
                Marked:     Is node marked ?
                Selected:   Is node selected ?

    Purpose:    This constructor initialises the nodes flags and links it to ContextNode in the
                direction specified by Direction. All neccesary tree links are updated.
    Note:       SetUpShape() must be called before the NodeRegularShape is in a state in which
                it can be used.
    SeeAlso:    NodeRegularShape::SetUpShape
    Errors:     An ENSURE will occur if ContextNode is NULL
