+/**
+ * Class Civi
+ *
+ * The "Civi" class provides a facade for accessing major subsystems,
+ * such as the service-container and settings manager. It serves as a
+ * bridge which allows procedural code to access important objects.
+ *
+ * General principles:
+ *  - Each function provides access to a major subsystem.
+ *  - Each function performs a simple lookup.
+ *  - Each function returns an interface.
+ *  - Whenever possible, interfaces should be well-known (e.g. based
+ *    on a standard or well-regarded provider).
