All Implemented Interfaces:

Serializable, ITreeProvider<Foo>, IDetachable, IClusterable
```
public class FooProvider
extends Object
implements ITreeProvider<Foo>

A provider of Foos. For simplicity all foos are kept as class members, in a real world scenario these would be fetched from a database. If Foos were Serializable you could of course just keep references in instance variables.
