HCL_Recorder defines an interface for "recorder" objects, used principally for recording intermediate results during an iterative process. Its Record method takes a vector argument; any derived class will impement a storage method appropriate to a concrete vector type. Disk image of the recorded data might be created on the fly, or during destruction of the Recorder object.Usage: instantiate a recorder object corresponding to the concrete vector class used in the iteration. Pass this object to the constructor of the iterative method (this of course presumes that the iterative method is set up to record intermediate results, and so taks a Recorder object as an argument to its constructor). Then use the PlayBack method to extract intermediate iterates after termination of the iteration.
