### Le Storage
LeStorage is used to store objects into json files, and it can also be used to synchronize those objects to a django server properly configured.
Here are the most important classes:
- StoredCollection: stores object of one class in a json file
- SyncedCollection: stores object of one class in a json file and synchronizes changes with the server
- ApiCallCollection: provision HTTP calls and tries to execute them again
- StoreCenter: The central class to manages all collections through Store instances
