Dino dex 2nd Refactor

DinoDex refactor based on comments from previous pull request.

The DinoDex has a command line interface. Run the "main.rb" script to initialize the CLI.
Perhaps you can construct a `CSVtoDinos` with a list: `[joes_csv, pirate_bay_csv]` then call the methods `normalize` and `to_hash_array` within it. It will clean up lines 5 and 6 and truly delegate the responsibility of conversion to `CSVtoDinos`.
