Flatten Array

Take a nested list and return a single flattened list with all values except nil/null.

The challenge is to write a function that accepts an arbitrarily-deep nested list-like structure and returns a flattened structure without any nil/null values.

For Example

input: [1,[2,3,null,4],[null],5]

output: [1,2,3,4,5]

Setup

There are two different methods of getting set up to run the tests with Objective-C:

Both are described in more detail here: http://exercism.io/languages/objective-c

Submitting Exercises

When submitting an exercise, make sure your solution file is in the same directory as the test code.

For example, if you're submitting Bob.m for the Bob exercise, the submit command would be something like exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m.
