TMBOY 44:c1d8923072ba 32 * the autoloader will first look for the class under the component/
TMBOY 44:c1d8923072ba 33 * directory, and it will then fallback to the framework/ directory if not
TMBOY 44:c1d8923072ba 34 * found before giving up.
TMBOY 44:c1d8923072ba 35 *
TMBOY 44:c1d8923072ba 36 * This class is loosely based on the Symfony UniversalClassLoader.
