Description:

The dust_config generator creates YAML file in your config
directory and an initializer to load this config. The config has a
separate section for each environment. This is a great place to put
any config settings you don't want in your app.

The config is loaded into a constant called APP_CONFIG by default,
this changes depending on the name you choose to pass the generator.
Use this constant to access the config settings like this.

APP_CONFIG[:some_setting]

Examples:

rails generate dust:config

    Config:      config/app_config.yml
    Initializer: config/initializers/load_app_config.rb

rails generate dust:config passwords

    Config:      config/passwords_config.yml
    Initializer: config/initializers/load_passwords_config.rb
