This package can generate permutations from input data strings.

There is one class that can parse a string that contains groups of numbers that relate one main number with a group of several numbers. Then it can process the related numbers list and finds how many programs are in the list that contain a given program ID.

Another class can take a string as input with groups of values that start with a letter that defines 3 possible actions:

- Spin will make combinations of numbers from the given numbers by moving first to the last or maintain their original order.
- Exchange will make combinations of numbers at 2 positions by exchanging their places.
- Partner will make combinations of numbers by swapping their places.
