Interface Annealable

public interface Annealable

This class represents an annealable entity. The process for the Annealable is thus:

• The Annealer will ask the annealable to permute itself randomly. The Annealable then makes a Change memento which codifies the change, as well as the change's cost.
• If the Annealer decides to accept the new configuration, the memento will be passed back to the Annealable with commitChange()
• This process will be repeated, and the end result should be some sort of minimized cost.
