	jQuery delicious tag search interface
	Version 1.0 (09/30/2009)

	Author: Heidi Hysell (hello@heidihysell.com)

	About:
		This plugin takes a listing of tags, places them into a tag cloud and uses that tag cloud as a navigation mechanism.
		It allows the user to search on multiple tags through and or searchs and filters further results on other tags selected.

	API:
		// tells the application to start following the piece of content for the logged in user
		$.deliciousTagSearch.getTagsForUser
		     format: "json", // format of results to return
		     username: "heidihysell", // person whom we're returning results for
		     envUrl: "http://feeds.delicious.com/v2",
		     successCallback: getTagsSuccess,	// returns item if it saved successfully (make sure item id is not null)
		     failureCallback: getTagsFailure // if ajax failed then we get sent to this function
		     
	Example Usage:

		$.followManager.getContentUserIsFollowing({
			successCallback: contentListSuccess,
			failureCallback: contentListFailure,
			page: 1,
			pageSize: 20,
			sort: "RecentlyAdded"
		});

		function contentListSuccess(list) {
			// perform updates on success
		}
		
		function contentListFailure(list) {
			// perform updates on failure
		}
