/** @brief CCLabelTTF is a subclass of CCTextureNode that knows how to render text labels
 *
 * All features from CCTextureNode are valid in CCLabelTTF
 *
 * CCLabelTTF objects are slow. Consider using CCLabelAtlas or CCLabelBMFont instead.
 *
 * Custom ttf file can be put in assets/ or external storage that the Application can access.
 * @code
 * CCLabelTTF *label1 = CCLabelTTF::create("alignment left", "A Damn Mess", fontSize, blockSize, 
 *                                          kCCTextAlignmentLeft, kCCVerticalTextAlignmentCenter);
 * CCLabelTTF *label2 = CCLabelTTF::create("alignment right", "/mnt/sdcard/Scissor Cuts.ttf", fontSize, blockSize,
 *                                          kCCTextAlignmentLeft, kCCVerticalTextAlignmentCenter);
