needs objectives, instructions

"parts of the Ruby Assessment were a little confusing---like creating a nested array by separating the species of animals---it was not clear how to determine their species with code." ~student

it is the animal_sorter.rb, which needs more instructions!

This can allow for some weird solutions.

Let's make the specs take the criteria for sorting on initialization. Something like

animals = ["fox", "badger", "whale"]
criteria = {sea: ["whale"], land: ["fox", "badger", "cat"]
animal_sorter = AnimalSorter.new(animals, criteria)
animal_sorter.to_a # => [ ["whale"], ["fox", "badger"]]

Or maybe sort into hashes instead.

This one needs a solution. Also, the code could be better.

The normalize_path method returns can return nil. We want a normalized, absolute path returned.
