// The movement information is based on the article
// "Movement Limits Tim's Host: How far can you go?" by Stefan Reuther:
// http://www.phost.de/~stefan/movement.html
// Thanks to McNimble for suggesting improvements to version 2!
// 1. Fixed a line weight problem that caused this plugin to not play well with
// others such as Ion Storm Predictor.
// 2. Made some cosmetic improvements to make the Grav and HYP lines
// easier on the eyes.
// Improvements to Version 3:
// 1. This version includes connections that can be reached via "inexact"
// movement (i.e., movement where you don't end up at your waypoint)
// The inexact movement displacements are partly taken from Reuther's document
// and partly taken from new calculations using the Nu client source code.
// 2. These "inexact" connections are shown in purple.
// 3. The W9Connect tool now shows "regular" connections (i.e. the same ones
// shown by the Nu client) in gray and "hidden" connections in a different
// color.
// Features:
// 1. The GravConnect tool shows paths between planets that can be reached by
// gravitonic connections. Paths that can be reached by non-gravitonic
// engines via normal connections are not shown. Special "inexact"
// connections that can only be reached by setting a waypoint that can't be
// reached in a single turn are shown in a differnt color (purple).
// 2. The HYPConnect tool shows paths between planets that can be reached by
// hyperjump connections.
// 3. The W9Connect tool is an improved version of the built-in connections
// tool that shows normal connections (gray), hidden connections (orange)
// and special "inexact" connections that can only be reached by setting a
// waypoint that can't be reached in a single turn (purple).
// Instructions: Click the "GravConnect", "W9Connect" or "HYPConnect" items on
// the Map Tools menu to turn these features on and off.
