Log:
Add lots more doc... that exposed a problem with the core
algorithm in cases where objects have custom comparison functions
and use cell attributes in the calculation.  Also, found and fixed
problems with dirtiness detection in mutables like Dict and Set,
and added a new API call, dirty(), to fix it.  Still a bunch more
doc to go, but it's getting to be downright informative already.
