+/**
+ * A simple interface that defines the ability to perform and detect
+ * arbitrary methods, by use of a "selector" string.  The selector
+ * is a string constructed of a method name and an arbitrary number of 
+ * classes representing parameter types.  These are then concatenated 
+ * with a ":" separator.  The resulting string represents a full
+ * method signature, without reference to the implementing class.  This
+ * allows arbitrary classes to be interrogated as to the validity of a
+ * given method call (i.e. do they or their parents implement it).  It
+ * also then allows the method with the given signature to be invoked.
+ * 
+ * For example:
+ * <code>
+ *   if (a.respondsTo("doThing:java.lang.String"))
+ *       a.perform("doThing:java.lang.String",aString);
+ * </code>
+ *
