/*  This script will classify as many links as possible and assign CSS classes
    accordingly.  See the complete script documentation for usage and more details.

    Key acknowledgement goes to User:Anomie whose script (User:Anomie/linkclassifier.js)
    was used as an initial template structure to get up an running quickly with MW api. Go 
    check it out if you're interested in a lot more ways to classify and color various MW links.
