 * Plugin forCheck

 * http://www.filipekiss.com.br/forCheck
 *
 *
 * Release 1.2
 * June, 03 - 2008
 *
 * Changelog for 1.2
 *
 * Added support to 'select' type fields
 *
 * Release 1.0
 * May, 06 - 2008
 *
 * Changelog for 1.0
 * First Release
 *
 * Usage: 
 * The requirements to fill the field are defined through pseudo-classes.
 * You Specify a class for the plugin and you may also specify any other class for styling your input field
 *
 * Pseudo-Classes Allowed
 * forCheck[*] - for any allowed data, but a required field (usernames, etc)
 * forCheck[int] - number field. you may leave this in blank. otherwise you should fill with a number
 * forCheck[str] - string field. no numbers or symbols allowed. (including spaces)
 * forCheck[email] - validate an email. accepts @ and also [at]
 * forCheck[password] - here's the real deal. i've started this plugin just because I needed to validate a password AND a confirmation field. So you give your password this class
 * and give you confirmation field the confirmation (forCheck[confirmation]) class. Done! It will check them! If they match, you're good to go. Otherwise, 'The passwords do not match'
 * forCheck[select] - Check to see if a select is valid. A value equal 0 will be made invalid. a value different will be true.
 *
 * Future Classes (Or, ToDo list, as you wish)
 * date - date Validation. Probably mm/dd/yyyy
 * [Support for FCKEditor] DONE!
 * 
 * 
 *
 * Notes:
 *
 * To make a required field and also a 'value type' verification just add an '*' after the type in the class name;
 * For example:
 * forCheck[email] denotes a simple, but not required, e-mail validation
 * forCheck[email*] denotes a required field. First it will check if it's filled. Then, it will check for a valid e-mail
 *
 * If you use an inexistent class, for example, forCheck[someClassHere], the plugin will simple ignore it. However
 * if you use an inexistent class followed by a '*' (forCheck[someClassHere*]), the plugin WILL ASK for content,
 * and WILL NOT allow the submition if the field is not filled.
 * This IS NOT a BUG.
