 * This class defines the controller periods for instantiating the whole elevator
 * (makeAll) and also a reflection interface that is used by the simulator to
 * process configuration (.cf) files.
 *
 * Parameters:
 * boolean verbose - whether or not verbose output is printed from the controllers.

     * Instantiates the controllers.
     *
     * Descriptions of the objects are read from a file.  Each line of
     * the file is expected to contain all of the arguments expected by the
     * Control object's constructor, in the order the Constructor expects them.
     * The first word on each line must be the name of the class of the
     * Controller.  So, one could instantiate a DriveControl object by including
     * a line like this:
     *
     * <pre>
     *      DriveControl 8 100000 true
     * </pre>
     *
     * The effect will be the same as calling the constructor:
     *
     * <pre>
     *      DriveControl(8,100000,true);
     * </pre>
     *
     * This method uses Java reflection, so you need Java 1.5 or later to use it.
