# add the other files to your django app and migrate

# I called my app 'issues'; so change issues to your app name in case you choose another one

# there are 5 models which realize state machine bindings to django models in different ways
# Item: add a transitions.Machine instance to each record/item
# ItemSingleton: add each model to a global transitions.Machine
# ItemSingletonSet: Extend transitions.Machine to use set instead of list to store models; this increases look up speed in add_model
# ItemNoMachine: just a minimal model without a state machine (for referencing purposes)
# ItemFysom: add a customized fysom machine to each record/item
