Description
------------------------------------------------------------------------------

Tag Handler is a jQuery plugin used for managing tag-type metadata.

------------------------------------------------------------------------------
Basic Usage Instructions
------------------------------------------------------------------------------

* Tag Handler must be attached to one or more <ul> tags in your HTML.

* To add a tag, click on the tag box, type in a name, and hit enter or comma.

* Tags may be removed from the tag box by hitting backspace inside the box or
by clicking on the tag.

* The list of tags may be initialized in 1 of 3 ways:

1. By passing arrays of tag names as options to the plugin
("availableTags" and "assignedTags"); or,

2. By supplying a "getURL" for the tags to be retrieved via AJAX.

When using this method, the server must supply a JSON formatted array
named "availableTags" and optionally an additional array named
"assignedTags".

3. By supplying a "getURL" and initLoad: false.

When using this method, it will get the "assignedTags" from the array as in
method 1. When the user writes a tag, it will query the server searching for
similar tags.

Either way, the information from these 3 methods will be used in the
following manner:

availableTags: each item in this array will populate the autocomplete
drop-down list

assignedTags: each item this array will become a tag in the tag box

* Tags may be sent back to the server by supplying an "updateURL". In this case,
an array will be sent back to the server named "tags".

* You can define whether the user can create new tags or select tags only.

* You can define if the user can edit the tags.

* A sample CSS file is included that can be used to help with formatting tags.

Plugin Examples
------------------------------------------------------------------------------

Example 1: The Tag Handler will be initialized with no options and no default
tags:

$("#basic_tag_handler").tagHandler();

Example 2: The Tag Handler will be initialized with preset tags from the
assignedTags and availableTags arrays, and autocomplete will be
turned on:

$("#array_tag_handler").tagHandler({
    assignedTags: [ 'Perl' ],
    availableTags: [ 'C', 'C++', 'C#', 'Java', 'Perl', 'PHP', 'Python' ],
    autocomplete: true
});
