Class InformationModel

java.lang.Object
  java.util.Observable
      backend.information.InformationModel

All Implemented Interfaces:

java.util.Observer

public class InformationModel
extends java.util.Observable
implements java.util.Observer

InformationModel is a model of all the information that the user would like to see about our program It takes InformationNuggets and stores them appropriatly. If a class extends InformationNugget then it is perfectly alright to add it to the InformationModel
