Sum Arrays

Given an array of values, return the sum of the values.

Business Rules/Errata

Input must be an array.
The array may be nested more than one level.
All values must be integers.
Solutions shall not use built in methods to flatten the array to one-dimension.
As always, Ruby may be new for folks. Don't hesitate to reach out to Lee or the #code channel to ask for help with your environment!

One dimension:

sum_of_array([1,2,3,4,5]) => 15

Two dimensions:

sum_of_array([1,2,[1,2,3],4,5]) => 18

n dimensions:

sum_of_array([1,[1,2,[3,4],5],[6,7]]) => 29

If you're on a mac, ruby is installed. On windows it's possible through a couple of ways. Ruby Installer or other options

If you want to use bundler to install the test runner dependencies, more info can be found here

You will need 'rspec' if you want to run the tests. From the project src/ folder run either:

gem install rspec

or if you have bundler installed

bundle install

rspec spec --format doc

After your tests pass, copy your code into a new file githubname.ext in the solutions/ folder
Eg: My ruby solution would become a new file solutions/parhaml.rb
