// ==/UserScript==
 
 
 
 
//Put above inside Userscript definition if also want cpb on all *weapons* page, rather than only art_specific
//Do at own risk, since it will initiate lot of requests to obtain all repair costs, might get admin's attention
 
 
 
// 1] Detect Table
// 3] Catch Relevant Values: Price, Dura, Name
// 4] Parse Repair Cost, store to name so don't have to recalculate
// 5] Attach form asking repair rate
// 6] Calculate CPB
// 7] Add Cpb, Repair till, and number of battles in Columns
// 8] Add sort abiility
// 9] Make CPB sort option part of dropdown
 
// (Maybe) 
// Add generic CPB calculator above page
// Contact Author with more ideas.
