  11  * Create a process list
  12  * contains the data for the process list
  13  * tells the height of the process list widget
  14  * provides methods to add/remove process from the list
  15  *      note : the sync with drawing is left to the caller.
  16  * provides helper function to convert a process unique identifier to
