/**
 * Bean Repository
 *
 * This class represents a repository of bean's and the means to get and
 * set there instances.
 *
 * This class uses a {@link BeanIdRegister} to optimize the access performance. If
 * all the {@link BeanId} objects are registered with the BeanIdList before this object
 * is created then you get direct access performance. If you regularly register new
 * {@link BeanId} objects with the {@link BeanIdRegister}, after this object is created
 * then the BeanRepository needs to sync up with the {@link BeanIdRegister}. That
 * sync process takes some time, so it is adviced to register all the BeanId's up front.
 *
 * Only {@link BeanId} objects from the {@link BeanIdRegister}, which is set on
 * this BeanRepository, can be used with almost all of the methods.
 *
 * For ease of use it is also possible to get the bean by it's beanId name. This has however
 * not the direct access performance because a Map lookup is done. It is advised to use
 * the {@link BeanId} to get the bean from the repository.
