/** 
 * TestFunctionStub is the base class for unknown functions. 
 * Each framework will need to implement its own subclass of
 * TestFunctionStub. 
 *
 * The interface is left very minimal so as to not place
 * any constraints on how a framework might specify the basis.
 * When a framework needs any information about the
 * unknown function, it will have to get it by downcasting
 * to the appropriate framework-specific subclass.
 *
 * <h4> Writing a TestFunctionStub subclass </h4>
 *
 * For purposes of interaction with the Sundance core, no 
 * additional methods are required.
 * However, most frameworks will require extensions to 
 * TestFunctionStub that can supply the framework with information
 * on the basis used by the unknown func. See the
 * demo and standard frameworks for information on how to do this.
