adds three methods - one to click the area,
 another to return the area element, and another to check the area's existence.

 @example
   area(:message, :id => 'message')
   # will generate 'message', 'message_element', and 'message?' methods

 @param [Symbol] the name used for the generated methods
 @param [Hash] identifier how we find an area.
 @param optional block to be invoked when element method is called
