Examples of LayoutController

org.gephi.layout.api.LayoutController
A LayoutController is the one responsible for controlling the states of the {@link LayoutModel}. It always controls the current workspace model.
This controller is a singleton and can therefore be found in Lookup:
```
LayoutController lc = Lookup.getDefault().lookup(LayoutController.class);
```
