Extend Project 1 to use advanced data structures and support sorting on various keys.

Elaboration:

1. Required data structure - the advanced data structure I want you to implement is a multi-tree with the following levels:

1. Library - Level 0 2. Author - Level 1 3. Book - Level 2 4. Journal - Level 2

2. Use the Map class to support efficient instantiation linking of the classes used in Project 1. 3. Implement comparators to support sorting:

o books by title, price, index o journals by (added fields) volume and number, date and issue o authors by name, index o The sorting should be within the group - books and journals corresponding to each author

(in the case of journals we consider the editors as authors). Extend the GUI from Project 1 to allow the user to:

o sort by the comparators defined in part 2. Again, the GUI elements should be distinct from the other classes in the program.
