Run first: 
- pick_mutants
- tables/faults (check methods and distributions)
- instr_mutants (optional)

Args: 
- <mut dir>, the dir resulting from pick_mutants or instr_mutants (absolute path) 
- <pkg dir>, the dir in which to place the created packages (absolute path)
- <app>, the application (cws=crosswordsage-0.3.5 or fm7=freemind-0.7.1 or fm8=freemind-0.8.0)

Constants: 
- <min tst len> & <max tst len>, the minimum and maximum test-case length (depends on the application)

Affects: 
- <pkg dir>

Creates in <pkg dir> a set of packages, which are zip files each containing: 
- mut_class, a dir containing the class file(s) from <mut dir>
- mut_path.txt, a file containing the path to the class file in <mut dir>
- tst_len.txt, a file containing the length of test cases to be generated
Makes each of these files in the zip read-only."
