 * Phing subclass of the ErrorTracker class provided with PhpDocumentor to work around limitations in PhpDocumentor API.
 * 
 * This class is necessary because PhpDocumentor does directly output errors and
 * warnings occured during testing for undocumented elements to stdout.
 * This class is injected globally to force PhpDocumentor to use phing's logging
 * mechanism.
 * 
 * Obviously this is far from ideal, but there's also no solution given the inflexibility of the
 * PhpDocumentor design.
