The Session layer of Lithium inherits from the common `Adaptable` class, which provides
the generic configuration setting & retrieval logic, as well as the logic required to
locate & instantiate the proper adapter class.

In most cases, you will configure various named session configurations in your bootstrap
process, which will then be available to you in all other parts of your application.

Each adapter provides a consistent interface for the basic session operations like `read`,
`write`, `delete` and `check`, which can be used interchangeably between all adapters.

For more information on `Session` methods and specific adapters, please see their relevant
documentation.
