* Implements an extension to the SCR log manager that uses logger names to

* logger's bundle unlike the classic scr log manager that used the bundle's logger.
*
* <ul>
* <li>An ScrLogger will log with the name {@value #SCR_LOGGER_NAME}
* <li>A BundleLogger will log with the name {@value #SCR_LOGGER_PREFIX} + the
* bundle symbolic name
* <li>A ComponentLogger will log with the name {@value #SCR_LOGGER_PREFIX} +
* the bundle symbolic name + "." + component name
