Subject: [PATCH] It was not acceptable to call the class method from the
 static initializer because it caused the load and initialize methods to be
 called.  Some of the load and initialize methods used autorelease which would
 lead to warnings about memory leaks (true, though very benign). This version
 delays all Objective-C calls until InitializePosers().
