-/**
- * This class is specialized in retrieving loggers by name and also maintaining
- * the logger hierarchy. The logger hierarchy is dealing with the several Log-Levels
- * Logger can have. From log4j website:
- *
- * "A logger is said to be an ancestor of another logger if its name followed
- * by a dot is a prefix of the descendant logger name. A logger is said to be
- * a parent of a child logger if there are no ancestors between itself and the
- * descendant logger."
- *
- * Child Loggers do inherit their Log-Levels from their Ancestors. They can
- * increase their Log-Level compared to their Ancestors, but they cannot decrease it.
- *
- * <p>The casual user does not have to deal with this class directly.</p>
- *
- * <p>The structure of the logger hierarchy is maintained by the
- * getLogger method. The hierarchy is such that children link
- * to their parent but parents do not have any pointers to their
- * children. Moreover, loggers can be instantiated in any order, in
- * particular descendant before ancestor.</p>
- *
- * <p>In case a descendant is created before a particular ancestor,
- * then it creates a provision node for the ancestor and adds itself
- * to the provision node. Other descendants of the same ancestor add
- * themselves to the previously created provision node.</p>
