 /**

  * Represents an entity which can be modified.  A Modifiable records it's state when

  * it's created.  As long as the Modifiable remains in this state then invocations of

  * isModified() should return false.  If this state changes in a way which makes this 

  * Modifiable "dirty" then subsequent calls to isModified() should return true.

  * 

  * <p>It is up to the implementor of the Modifiable to determine the contract between

  * the Modifiable and the entities interested in it's modified status.  This could

  * include interested entities taking action on the Modifiable once it has become

  * modified which result in it's modified status being reset.  Another possibility is

  * for a Modifiable to be discarded once it has been modified.
