Class ~EntryBase~

This class must be the base of all node entries in this framework.

If "[_][_]GTREE[_]DEBUG"[4] is defined, the class will compile with a virtual destructor, which is used for further type checkings in some methods by using "dynamic[_]cast"[4] instead of "static[_]cast"[4] to avoid using incompatible entry and node types, e.g. inserting leaf entries into internal nodes.
