* Defines service registry contracts application are likely to want to utilize for
* configuring Hibernate behavior.
*
* {@link BootstrapServiceRegistry} is the
* Service registries are designed to be hierarchical. This works in 2 fashions. First registries can "hide" or
* "override" services from parent registries. It also allows granular building of registries as services
* become available.
*
* {@link BootstrapServiceRegistry} is the base service registry, intended to be built via
* {@link BootstrapServiceRegistryBuilder} if you need customization. For non-customized
* {@link BootstrapServiceRegistry} usage, the {@link BootstrapServiceRegistryBuilder} and
* {@link BootstrapServiceRegistry} can be bypassed altogether.
*
* Usually the next level in a standard registry set up is the {@link StandardServiceRegistry}, intended to be built
* by the {@link StandardServiceRegistryBuilder} if you need customization. The builder optionally takes the
* {@link BootstrapServiceRegistry} to use as a base; if none is provided a default one is generated assuming sensible
* defaults in Java SE and EE environments, particularly in respect to Class loading.
