Fixes #48 - Add Money Rails Gem

[rray524]

Checklist:

• I have checked money-rails is already added on gem file
• I have checked money_rails:initializer is already present inside config/initializers folder

Resolves #48

• I have additionally added dotenv gem file for env support

  group :development, :test do
  gem 'dotenv-rails'
  end

  which will be used to keep the database username & password hidden from the public: File path: config/database.yml

  development:
  <<: *default
  adapter: postgresql
  encoding: unicode
  database: backend_kc_development
  pool: 5
  username: <%= ENV["BACKEND_DATABASE_USERNAME"] %>
  password: <%= ENV["BACKEND_DATABASE_PASSWORD"] %>
  host: localhost
  port: 5432

  Description

  This library provides integration of the money gem with Rails.
