// todoList.h
//////////////////////////////////////////////////////////////////////////
//  todoList provides support for maintaining a simple list of tasks that
//  must be carried out.  Each task is represented by a single string,
//  which can contain as much or as little text as desired.  Tasks may
//  only be accessed in FIFO order.  The first task todo may be examined,
//  or removed from the list.  Newly added tasks are appended to the list.
//
//  The items in the todo list may be saved to file; the file will consist
//  of entries of the form "<seqno>:\t" followed by the text string for a
//  task.  The saved tasks are numbered, starting at zero.
//
//  The todo list may be initialized task by task, or loaded at once
//  from a file (formatted as described above).
