Create an application loading context.
The application environment.
The initial settings. These settings are merged with the settings from the loaded configuration files, and together form the initialConfiguration provided by the context. It is intended for use in dev mode, to allow the build system to pass additional configuration into the application.
Used to register hooks that run when the application stops.
If an application is loaded in dev mode then this additional context can be provided.
(Since version 2.7.0) Context properties have changed; use the default Context apply method or Context.create instead
