* Move some classes to separate files to avoid having a monstrous file with a dozen classes. * Remove weird underscores from class names. * Instead of prefixing members with underscores, specify visibility explicitly. * Rename c_style -> camelCase per coding conventions. * Throw exceptions instead of fataling out with trigger_error(). * Remove pointless constant used only once.
