// == Notes ==

// Created by Tsarugi (Artemis)

// Special thanks to Janarius for opening my eyes to Greasemonkey

//

//

// 2.0 Shopping List

// Added ability to track other players' buildings stock

//    and display info list on building > overview page

// Added Keyboard Shortcuts

// Added Price Guarding capability

//

// 1.5 Numerous Substantial Improvements :

// Improved Remaining Space calculation to account for manually entered values

// Improved Remaining Space calculation to account for original click fill usage

// Clicking on individual commodity name will auto insert max buy / sell value

// Added form reset button

// Mag Scoop useablility added

// Added Free Space tracking display for building, ship, and Mag scoop

//

// 1.2 Added funtionality to prohibit :

// selling produced commodities to building and

// buying supply commodities from building

//

// 1.0 Created on 12 / 16 / 2007

// A traders best friend

// Gives three buttons on building trade screen :

// 'Sell All' - Auto fills 'Price (sell) column based on amount in ship, building min/max and avaliable space

// 'Buy All' - Auto fills 'Price (buy) column based on min, produced commodities, and available space in ship

// 'Easy Button' - does both

//

// Does not work on one's own building

//

// == End Notes ==
