/**
 * PHLY - PHp LibrarY
 *
 * PHLY is a library of PHP classes designed with the following intentions:
 * - Loosely coupled; dependencies should be few, and no base class should be
 *   necessary.
 * - Extendible; all classes should be easily extendible. This may be via
 *   observers, interfaces, adapters, etc.. The base class should solve 80% of
 *   usage, and allow extensions to the class to fill in the remainder.
 * - Designed for PHP5 and up; all classes should make use of PHP5's features.
 * - Documented; all classes should minimally have excellent API-level
 *   documentation, with use cases in the class docblock.
 * - Tested; all classes should have (passing) unit tests accompanying them.
 * - Open source and commercial friendly; all classes should use a
 *   commercial-friendly open source license. The BSD license is one such
 *   example.
