Provider
A provider is an abstract definition of a storage mechanism. Every provider can set, get and delete content.
You can register a provider on the application object of storagestack.
ss.registerProvider(new BlockstackProvider());
Or when you want to use a pattern ...
ss.registerProvider(new BlockstackProvider(), '*-index.json');
Take a look in the core library to the provider interface.
