Convert Mock Digital Twin to be compatible with standard adapters (#144)

- Converts the Mock Digital Twin to be compatible with the standard adapters (fixes #143)
- Creates the standard Freyja application since it was convenient for testing (fixes #142)
- Removes any HTTP-based adapters that were used with the old implementation as well as deprecated examples

 ### Using Freyja
 
-To use Freyja, you will need to implement some adapters and write the main executable that will run the Freyja application.
+Freyja supports a default runtime that is integrated with a set of standard adapters. To build and run the Standard Freyja Runtime, run the following command:
 
-For a guide on how to get started quickly by running some minimal examples, see the [Quickstart Guide](docs/tutorials/quickstart.md).
+```shell
+cargo run -p freyja

-For more advanced topics on how to implement and use your own adapters, see the [Custom Adapters Guide](docs/tutorials/custom-adapters.md).
+This runtime will support the following set of standard adapters:
