+/**
+ * Container is a dependency injection container.
+ *
+ * It gives access to object instances (services).
+ * Services and parameters are simple key/pair stores.
+ * The container can have four possible behaviors when a service
+ * does not exist (or is not initialized for the last case):
+ *
+ *  * EXCEPTION_ON_INVALID_REFERENCE: Throws an exception (the default)
+ *  * NULL_ON_INVALID_REFERENCE:      Returns null
+ *  * IGNORE_ON_INVALID_REFERENCE:    Ignores the wrapping command asking for the reference
+ *                                    (for instance, ignore a setter if the service does not exist)
+ *  * IGNORE_ON_UNINITIALIZED_REFERENCE: Ignores/returns null for uninitialized services or invalid references
