           sub init {

DESCRIPTION

       Dancer::Object::Singleton is meant to be used instead of Dancer::Object, if you want your object to be a
       singleton, that is, a class that has only one instance in the application.

       It provides you with attributes and an initializer.

METHODS

   instance
       Returns the instance of the singleton. The instance is created only when needed. The creation will call
       the "init()" method, which you should implement.

   init
       Exists but does nothing. This is so you won't have to write an initializer if you don't want to. init
       receives the instance as argument.

   get_attributes
       Get the attributes of the specific class.

   attributes
       Generates attributes for whatever object is extending Dancer::Object and saves them in an internal
       hashref so they can be later fetched using "get_attributes".
