This is an iterator that moves over every MidiEvent in a Playable object. Each MidiEvent are delivered in time order. This is a use of the 'Iterator' design pattern in the GoF book.
Each kind of Playable object will provide an implementation of the PlayableIterator interface that knows how to iterate over that kind of object.

| PlayableIterator ()
| PlayableIterator |
Create a PlayableIterator. Client code will never call this member function.
Derived classes must attach themselves to the parent Playable object as listeners, and then implement Listener::deleted properly.

[virtual]
| const MidiEvent & operator* ()
| operator* |
[const]
Returns the next MidiEvent in the iterator

[virtual]
Moves the iterator to the given time position.
Parameters:
