Project boilerplate

While React itself doesn't enforce any specific project strucutre or setup for that matter, it's always better to have a boilerplate at disposal to kickstart a React project.

After studying some of the available boilerplates, we found react-slingshot from a Pluralsight Author coryhouse quite handy. However it is to be noted that it's just a recommendation and subject to personal preference and at some times project requirements.

Project Strucutre

# Flattens an array of arbitrarily nested arrays of integers into a flat array of integers
#
# Algorithm:
#   1. Iterate over each element in the array.
#   2. If the element contains nested array elements, apply the same function recursively to each elements.
#   3. For integer values, push them into a flat array
#
# @param array[Array], nested array to be flattened
# @return [Array], flattened array
def flatten(array)
