Code Evaluator Service

The goal of this project is to create and publish an API that allows users to evaluate code in different programming languages using isolated Docker containers.

Use cases for this project include an online IDE for pair programming, a remote interview tool and evaluation of challenges (like Make it Real), among others.

Before using this service users have to sign up so that they can grab a generated API Key that they have to use to authenticate the requests.

Assuming that the service is published in the domain http://eval.io/, it should be posible to make a POST to the path /v1/eval/<platform> where <platform> is one of the languages or platforms supported.

La clase Bank sería así:

class Bank
  def initialize
    @accounts = {} # acá vamos a almacenar las cuentas
    @seq = 0 # consecutivo para los ids de las cuentas
  end

  def open(name, initial_balance)

Para hacer algunos ejemplos de herencia, métodos y atributos de clase vamos a modelar un sistema de nómina para una compañía.

Empezamos con una clase Employee de la cual van a extender otras clases:

class Employee
  attr_reader :name, :email, :salary
  
  def initialize(attrs)
    @name = attrs[:name]
