 * These is something I did in my spare time to remember the sorting alhorithms out there

 * you can write in pure PHP. Even with optimizations and opcode cache (which I didn't do / take
 * into consideration), these scrips are orders of magnitude slower than PHP sort() - which is used
 * in PhpDefaultSort class.
