Provides runtime configuration information.

A runtime configuration is defined by a {@link ovm.core.stitcher.ServiceConfiguratorBase ServiceConfiguratorBase} subclass. The `ServiceConfigurator` holds the set of {@link ovm.core.stitcher.ServiceFactory ServiceFactory} instances defined in the current configuration. A `ServiceFactory` allows access to a particular set of {@link ovm.services.ServiceInstance ServiceInstance} objects, each of which defines a particular runtime service of the OVM: threading, event management, I/O etc.

The name "stitcher" comes from the early implementation days. Really the contents of this package could be relocated to `ovm.services` or a subpackage thereof.
