/**
* 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>
