/*
Browsing and editing graph is one of the most natural uses for an IKBrowser. This class defines a graph manager that automates the generic operations. End applications only need to specify the graph structure. The IKBrowserManager takes care of filling in a browser with the appropriate information, responding to editing and dragging, selecting paths, and so forth.
The class is designed to create an IKBrowserManager in pair with a single IKBrowser. Lord knows what would happen if one tried to switch the characteristics of an IKBrowserManager on the fly. Hence, there are no set methods to change either the root path or graphClassName. These should be provided at initialization time or via InterfaceBuilder.

The IKGraphNode protocol abstracts the methods that a class must implement to be browsable by an IKBrowserManager. The IKFolder class is the only IconKit class that conforms to this protocol.
