• Use standard Array and Enumerable methods
• Work with multi-dimensional arrays to gather information

Array collections of records in Rails are ubiquitous. It is pretty common in pure Ruby too to rely on low level data structures for organizing data. This exercise will take you through a series of spec that increase in difficulty, proving that arrays aren't always the best way to store data.

This project comes with a recommended Ruby version and a gemset. There is a Gemfile too. There is no real code to write. We are just going to be modifying, reading and creating hashes that live in our test world.
