    The Help Tool allows you to define help dictionaries for the widgets in

    window applications. The tool are able to run stand alone or in other master 

    applications like the GUI Painter and the Menu Editor.

    If the application responds to the selector #showHelp:aHelpText for:aView,

    this selector is called by the widget's view when the mouse cursor moves over. 

    If the application does not responds to that selector, and the activeHelp mode

    is enabled, an active help bubble is shown at the widget's view.

    [instance variables:]

        specClass       <Symbol>        class implementing the help spec

        specSelector    <Symbol>        selector returning the help spec

        dictionary      <Dictionary>    dictionary containing pairs of help keys/texts

        dictionaries    <Dictionary>    dictionary containing pairs of help spec classes/help dictionaries

        listSelection   <String>        current selected help key

        maxCharsPerLine <Integer>       maximum number of allowed characters per text line

        modifiedHolder  <ValueHolder>   value holder for setting as modified

        modified        <Boolean>       flag whether the help spec was modified
