// ----------------------------------- Credits ------------------------------------ //
//
// These javascript tools were inspired by
//      [[Wikipedia:WikiProject User scripts/Scripts/Formatter]]
// Some of the functions were created by modifying existing Formatter functions
//
// This script is intended to be complimentary to this script with very little
// to no duplication of function.
 
// ---------------------------------- Disclaimer ---------------------------------- //
//
// Use at your own risk and make sure you check the edit changes before you save
//
// Let me know [[User_Talk:Plastikspork]] if you find bugs!
 
// ----------------------------- Installing the Script ---------------------------- //
//
// (1) Open/Create your USERNAME/monobook.js page, where USERNAME is your username.
//     A quick way to get there is to go to your user page, then append
//     '/monobook.js' to the end of the URL.
//
// (2) Put the following command on your monobook.js page:
//          importScript('User:Plastikspork/whitespace.js');
//
// (3) Save the page and reload it by following the instructions at the top of your
//     monobook.js page.  For example, Ctrl+Shift+R in Firefox.
 
// ------------------------------- Using the Script ------------------------------- //
//
// (1) This is a collection of javascript functions which can be called from other
//     scripts.
//
//  Note: Some functions could run slowly on very large pages, but do 
//        always eventually complete in my experience.
