 * @author Stuart Langridge
 * @version 1.3
 *
 *
 * Basic calling syntax: jQuery("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
 *
 *   lclass
 *     a class that will be applied to the input field when it contains the
 *      label and removed when it contains user input. Defaults to labelified.
 *
