# Class for configuring the Renalware::Core engine
# http://stackoverflow.com/questions/24104246/how-to-use-activesupportconfigurable-with-rails-engine
#
# To override default config values, create an initializer in the host application
# e.g. config/initializers/renalware_core.rb, and use e.g.:
#
#   Renalware.configure do |config|
#    config.x = y
#    ...
#   end
#
# To access configuration settings use e.g.
#   Renalware.config.x
#
module Renalware
  class Configuration
    include ActiveSupport::Configurable

    # Force dotenv to load the .env file at this stage so we can read in the config defaults
