  Data Members
    private:

      Bool_t fState     Object's state - "a local copy"
      Long_t fOnValue   Value recognized as switched ON (Def=1)
      Long_t fOffValue  Value recognized as switched OFF(Def=0)
      Long_t fValue     Local copy of a value returned by called function

    protected:

            Bool_t fInitialized  True if either SetToggledObject or SetToggledVariable called - enables Toggle() method.
          TObject* fObject       The object this Toggle belongs to
      TMethodCall* fGetter       Method to Get a value of fObject;
      TMethodCall* fSetter       Method to Set a value of fObject;
            Int_t* fTglVariable  Alternatively: pointer to an integer value to be Toggled instead of TObjectl

Class Description

                                                                      
 TToggle                                                              
                                                                      
 This class defines toggling facility for both - object's method or   
 variables.                                                           
 Assume that user provides an object with a two-state field , and     
 methods to Get/Set value of this field. This object enables to switch
 values via this method when the only thing you know about the field  
 is the name of the method (or method itself) which sets the field.   
 This facility is required in context Pop-Up menu, when the only      
 information about how to toggle a field is a name of methhod which   
 sets it.                                                             
 This Object may be also used for toggling an integer variable ,      
 which may be important while building universal objects...           
 When user provides a "set-method" of name SetXXX this object tries   
 automaticaly find a matching "get-method" by lookin for a method     
 with name GetXXX or IsXXXfor given object.                           
                                                                      

 TToggle default constructor. You have to initialize it before using
 by making a call to SetToggledVariable() or SetToggledObject()

 Initializes object for use with a variable - you pass it via reference
 so it will be modified by Toggle.

 Returns the state of Toggle according to its current value and
 fOnValue ; Returns true if they match.

 Sets the value of toggle to fOnValue or fOffValue according to passed
 argument.

 Sets the value of toggle and modifies its state according to whether
 the value is equal to fOnValue.

 Toggles the Values and State of this object and connected data!

 Initializes it to toggle an object's datamember using this object's method.
