-  * Implements a history for a text box. 
-  * Usage:
-  * <input id="some_input_element">
-  * var entry = document.getElementById("some_input_element)"
-  * var HistObj = new EntryHistory(max_lines, widget);
-  *
-  * By default, the constructor assigns the default onkeyup function
-  * handler to the passed in widget, but you can also do:
-  * entry.onkeyup = f; (where f = function(event) { etc } )
