It is recommended to set these attributes indirectly
through a MiscTreeDiagram instance which controls the tree.
The style of a node is defined by attributes saved in four different classes: MiscLayoutTree,
MiscDiagramTree, MiscNodeStyle and MiscTreeStyle. Every MiscDiagramTree instance holds
an instance of MiscNodeStyle and the MiscTreeDiagram instance controlling the tree holds
an instance of MiscTreeStyle."*/
