Moved existing code into new module.
Established a new module for the CLI.
Converted the main directory into a parent POM for the project.
Added count and generate commands for the CLI.

syntax:

    comb generate -t <TYPE> -k <SIZE> -d <DOMAIN>
    comb count -t <TYPE> -k <SIZE> -d <DOMAIN>

where:

- TYPE is the either c for combinations or p for permutations
- SIZE is the size of the elements of the combinatoric
- DOMAIN is the domain for the operation
Updated command line syntax.  Now combinations and permutations each have a switch.

    comb generate [-c | -p] -k <SIZE> -d <DOMAIN>
