local p = {}
-- Based on the wikicode in http://en.wikipedia.org/w/index.php?title=Template:Rating&oldid=486677637

-- Arguments
-- The first unnamed parameter is the number of the rating received.
-- The second unnamed parameter is the maximum possible for the rating system.

-- Optional arguments
-- "score" is used to change the alt text when mousing over the rating, in the case where "x/x" is not accurate or more information can be added.
-- "full", "half" and "empty" are used to change the images from the default stars to images you specify for each case.
-- rating= should be used to name the new rating symbol if you change the images.
-- rating-plural= accepts non-standard pluralization in the tooltip to be used instead of adding "s" in simple cases.
-- size= can be used to adjust the width at which the rating symbols display.

-- Testing with the Debug console:
-- frame = {} 
-- frame.args = {1,2}
-- =p.whole_and_half(frame)
