# Creates a new node or loads an already existing Neo4j node.
#
# You can use two callback method to initialize the node
# init_on_load:: this method is called when the node is loaded from the database
# init_on_create:: called when the node is created, will be provided with the same argument as the new method
#
#
# Does
# * sets the neo4j property '_classname' to self.class.to_s
# * creates a neo4j node java object (in @_java_node)
#
# If you want to provide your own initialize method you should instead implement the
# method init_on_create method.
#
# === Example
#
# class MyNode
# include Neo4j::NodeMixin
#
# def init_on_create(name, age)
# self[:name] = name
# self[:age] = age
# end
# end
#
# node = MyNode.new('jimmy', 23)
