[Chicken-users] "coops" object system

[Felix]

Hello!

This announces yet another object system, named (obvious but somewhat lame): 
"coops"

Features:

- the highlevel API is compatible to tinyclos
- based on Dorai Sitaram's "ScmObj"
- multimethods
- multiple inheritance
- before/after/around methods
- implicit generic procedure definition
- full integration with SRFI-17 setters (generic procedures can be defined
  on setters)
- reader:/writer:/accessor:/initform: slot options
- faster slot-access than tinyclos
- faster than tinyclos for repeated invocation of the same method
- relatively clean code, even with optimizations (tinyclos has been
  optimized into an inscrutable mess, somehing for which I have to take 
  the full responsibility)

Limitations:

- no MOP (which is mostly used for hacks, anyway)
- still slower than tinyclos for alternating invocations of the same generc
  procedure with different argument classes)
