Makes the fabricated class implement the provided service interface. The interface will be added, and all methods in the interface will be delegate wrappers. If toString() is not part of the delegate interface, then an implementation will be supplied that returns the provided string. This method is used when creating objects that proxy their behavior to some other object. @param serviceInterface the interface to implement @param delegateExpression the expression used to find the delegate on which methods should be invoked. Typically a field name, such as "_delegate", or a method to invoke, such as "_service()". @param toString fixed value to be returned as the description of the resultant object
