NAME
       Dancer::Object::Singleton - Singleton base class for Dancer

SYNOPSIS
	   package My::Dancer::Extension;

	   use strict;
	   use warnings;
	   use base 'Dancer::Object::Singleton';

	   __PACKAGE__->attributes( qw/name value this that/ );

	   sub init {
	       my ($class, $instance) = @_;
	       # our initialization code, if we need one
	   }

	   # .. later on ..

	   # returns the unique instance
	   my $singleton_intance = My::Dancer::Extension->instance();

DESCRIPTION
       Dancer::Object::Singleton is meantto 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".
