/********Class Graph_Pane******/
/*
  this class contains the graph as well as the other components
  that either communicate with the graph or alter the graph.
  Components:
  1 Menu Bar 
    -- Graph representation menu
  2 Title on a panel
  3 Time Value display
  
  This class is also an event listener for these components
  To make Graph_Pane communicate the marked time to the top-level container,
  the container needs to be passed as an object to this class using the second
  constructor, the event code in the mouseClicked function needs to be changed 
  - add the necessary function to the container and utillize it in the if 
    statement, replace the (Graph_Pane) explicit typecasting with the
    (container class) type cast. which basically means that you need to also
    provide a double variable in the container called markd_time.
