+/**
+ * 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>
+ *
