// @version 2.4
// ==/UserScript==
// Version 1.0 = grab params from displayed design, calculate targeting score and display it
// Version 2.0 = added support for "dynamic" display, i.e. during design creation
// Version 2.1 = fixed sliders and input fields for armor/shields
// Version 2.2 = fixed keyboard input
// Version 2.3 = fixed float vs. int speed issue, and fixed score display during ship design
// Version 2.4 = fixed formula for H5 (it has been changed, apparently!)
// Version 2.5 = fixed html/css changes in H6
// ----------------------------------------------------------------------------------------
// Note for v2.4:
// TS value calculated (and displayed) on View ship class screen is not accurate, i.e. real
// TS is probably lower. This is because formula is using 'Hull mass', not 'Total mass' and
// there is no way to find you what hull mass exactly is. This is only possible on Ship
// design screen, for wich TS displayed should be correct. Sorry for inconveniece!
