-/**
- * jQuery.labelify - Display in-textbox hints
- * Stuart Langridge, http://www.kryogenix.org/
- * Released into the public domain
- * Date: 25th June 2008
- * @author Stuart Langridge
- * @version 1.3
- *
- *
- * Basic calling syntax: $("input").labelify();
- * Defaults to taking the in-field label from the field's title attribute
- *
- * You can also pass an options object with the following keys:
- *   text
- *     "title" to get the in-field label from the field's title attribute 
- *      (this is the default)
- *     "label" to get the in-field label from the inner text of the field's label
- *      (note that the label must be attached to the field with for="fieldid")
- *     a function which takes one parameter, the input field, and returns
- *      whatever text it likes
- *
- *   labelledClass
- *     a class that will be applied to the input field when it contains the
- *      label and removed when it contains user input. Defaults to blank.
- *
