/**
 * 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 at compilation time (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
 *  * RUNTIME_EXCEPTION_ON_INVALID_REFERENCE: Throws an exception at runtime
