+
+ While spdlog is great, my need for logging is limited to compile

+ the logging facility implemented in LibreOffice which was done by
+ Stephan Bergmann. That said, the one in ixion is very simplified
+ version of LibreOffice's logging.

+
+ This also resolves the confusion between the interface and its

+ For now TypeError is raised. But in the future we should raise our

+Date: Mon Mar 7 01:43:07 2011 -0500
+
+ Removed usage of pointer-to-name map from the thread manager.
+

+ around a separate cell pointer to name mapping object.
