Ratings

  Simple and efficient object rating system

  install
   
    if you want the cmf tool variant

        add an external method standard cmf style

  requirements

    scalable

	allow numeric ratings, once per authenticated user.


	should support future data mining ie.

	  - data analysis of ratings to provide users with
	    packages they will probably like.

  implementation

        the ratings objects are stored local to the content
	with an IIBTree mapping hash(user_name) to their vote.

	the rating tool is a cmf style tool that allows 
	for a consistent api to to access a contents ratings,
	AND maintains a list of the highest rated objects. the list
	utilizes a pluggable ranking algorithm to allow for tuning
	of the highest rated list. this list is maintained as 
	an OOSet. a catalog implementation was not used because
	it would not be as scalable, imo.
