// Defaults: len = 15;
// tname = "span";
// tclass = "trunc";
// tooltip = true;
// chr = "…";
//
// The function will run through every tag you specify with the tname
// variable, then, if it's class attribute matches the one you specify with
// tclass, then it will search though it's innerHTML for words longer than the
// value you specify in len. If it finds them, it will truncate them to len,
// and add chr onto the end. It will bypass HTML tags, but will affect the
// inside of them. Specifically, if you did an tag with a URL:
// http://www.google.com/
// and len was 10, then it would truncate the text inbetween the tag to
// "http://www" while still retaining the tag in full.
//
// If you specify the tooltip variable to true, then it will add a tag
// around the replaced text with a title attribute saying what the truncated
// text was.
function RIcutwords() {
len = 15; // Change to the length desired for cutting.
tname = "span"; // Change this to the tag name you will use.
tclass = "trunc"; // Change this to the class="" attribute of the tags to be modified.
tooltip = true; // true for tooltip of what the word is; false for no tooltip.
chr = "…"; // The character to add to the end. Alt + 0133 = … (three dots)
