Add random_permutation

[samderanova]

What is this Python project?

random_permutation is a module that can provide a random permutation of a range of numbers from 0 to a given n-1 inclusive.

What's the difference between this Python project and similar ones?

While there are projects and individual functions/methods that generate permutations of objects, they generally do not work well for extraordinary large ranges as the resulting permutation would be directly stored and exhaust available memory. This library takes a different approach by storing the permutation in a generator object, making it extremely efficient to not only generate, but also to store and iterate over.
