menu_aaaOpen

  menu_aaaOpen is the sigTOOL menu gateway to the scOpen function

  scOpen is called to load data from a kcl file into sigTOOL using memory 
  mapping via the MATLAB memmapfile function

  Examples:
  menu_aaaOpen(0) passes back details needed to populate the File/Open menu
  item in the sigTOOL main figure window

  menu_aaaOpen() with no input arguments invokes uigetfile to open a sigTOOL
  kcl file. The function then populates the figure window with data from 
  the opened file or, if the figure is already populated,invokes another
  instance of sigTOOL. This is the format of the call to menu_aaaOpen from
  the sigTOOL menu bar (i.e. the menu item's 'callback')

  The sigTOOL channel array is placed in the figure's application data area
  in a field labeled 'channels'.
