var sanitisedHtml = janitor.clean(html);

A configuration object.

tags defines a whitelist of elements that are allowed in the sanitised output. Each entry in the map should be the name of the element and the attributes that a valid for the element.

E.g. {tags: { p:{}, a: { href: true} }} would limit the valid HTML subset to just paragraphs and anchor tags. Paragraph tags would have all attributes stripped, and the anchor tags would only have the href attribute preserved.
