+/**
+  * This class is the abstract superclass of all classes that implement
+  * the concept of a permission.  A permission consists of a permission name 
+  * and optionally a list of actions that relate to the permission.  The
+  * actual meaning of the name of the permission is defined only in the
+  * context of a subclass.  It may name a resource to which access permissions
+  * are granted (for example, the name of a file) or it might represent
+  * something else entirely.  Similarly, the action list only has meaning
+  * within the context of a subclass.  Some permission names may have no
+  * actions associated with them.  That is, you either have the permission
+  * or you don't.
+  *
+  * The most important method in this class is <code>implies</code>.  This
+  * checks whether if one has this permission, then the specified
+  * permission is also implied.  As a conceptual example, consider the
+  * permissions "Read All Files" and "Read File foo".  The permission
+  * "Read All Files" implies that the caller has permission to read the
+  * file foo.
+  *
+  * <code>Permission</code>'s are not dynamic objects.  Once created, a 
+  * <code>Permission</code>'s name and action list cannot be changed.
+  *
