+   * HOW TO ADD NEW COMPONENTS:
+   *
+   * If you want to add a new, simple component, that you will use in
+   * logging statements, simply create a new class variable that
+   * instantiates this class, and choose an appropriate string name
+   * and a integer constant not used by any other component level.
+   *
+   * For example, if my component had to do with 'frobbing', I would
+   * add this entry below:
+   *
+   *   private static final Component FROBBING = new Component ("FROBBING", 7);
+   *
+   * Then, I would update the component 'EVERYTHING' to have and end
+   * index ONE GREATER THAN the index of the new component.
+   *
+   * ADDING NEW COMPONENT CLASSES:
+   *
+   * A "component class" is a run of more than one component, which can
+   * be enabled all at once. EVERYTHING and SSL are examples of component
+   * classes. To add a new class, create a new component with a start index
+   * equal to the index of the first member component, and with an end
+   * index equal to the index of the last member component plus one.
