# this pattern of declaring methods in a module and then including into a class means that the methods can be used directly from the module
# eg. ExtendObject::attr_from_json(json,object)
# or on the class it is included into
# eg. model.attr_from_json(json)
module ExtendObject
module_function # this makes the methods accessible on the module as well as instances when the module is included into a class
public
def attr_from_json(aJsonObject,aObject=nil) # only give second argument when used like ExtendObject::attr_from_json
