This change refactors the GraphController to use the GraphAccess only with a single call that returns a Graph. The Graph
contains all information for visually representing the active Token with all parent and child nodes and edges. This
reduces coupling of the data and logic tiers.
Added simple layouting functions (implementations for simple grid and circle layout).
Also the graph displays class members and connections (edges) to or from them "correctly" now.

By now the graph displays the active node, without neighbours or anything, and clicking a node sets the active token id to the clicked nodes id.
