// Greasemap
// version 0.6 BETA!
// 2005-07-18
// Copyright (c) 2005, Vinq, LLC
// Released under the GPL license
// http://www.gnu.org/copyleft/gpl.html
//
// --------------------------------------------------------------------
//
// This is a Greasemonkey user script.
//
// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.
//
// IF YOU ARE UPGRADING FROM A PREVIOUS VERSION OF GREASEMAP, go to
// Tools/Manage User Scripts and manually uninstall the previous
// version before installing this one. Sorry, this is a limitation
// of Greasemonkey.
//
// To uninstall, go to Tools/Manage User Scripts,
// select "Greasemap", and click Uninstall.
//
// --------------------------------------------------------------------
// WHAT IT DOES:
//
// On any web page that doesn't match *vinq.com*
// - searches for addresses, zip codes, and geolocation tags within the page
// - if it finds any,
// - injects a Google map using the new Google Maps API at the top
// of the page, including credit to Google and to Vinq Greasemap
// --------------------------------------------------------------------
// CHANGELOG:
// 0.6 2005-07-21 Removed GM_ functions (menu choice) from script, due to greasemonkey problem
//
// 0.5 2005-07-18 Don't add DHTML output until onload time.
// (As suggested in the first tip at:
// http://greasemonkey.mozdev.org/authoring.html .)
// (Jeff Dairiki)
// Make address matching more forgiving, working also for
// zipcode-less addresses with no comma before the state abbrev
//
// 0.4.gtd1 2005-07-18 DOM-ify the DHTML generation code.
//
// Fix some bugs which express themselves when
// other greasemonkey scripts are also adding
// content to the top of the page: the
// close-map X box wasn't position properly;
// clicking the close-map X box sometimes deleted
// the other scripts output rather than the greasemap.
// (Jeff Dairiki)
//
// DOM-ify the meta-tag parsing code. (Also
// remove exact duplicates from the spots list,
// so that if a page has both a geo.position and
// and ICBM tag, it doesn't get counted twice.)
//
// 0.4 2005-07-14 8pm New link to show the same map in a new, big window
// On big map, addresses link to show infowindow on that pin
// On big map, infowindow shows address + directions form
// Parse geo:lat and geo:lon tags from Flickr + other sites
// Parse U.S. addresses which lack a zip code, as long as the state
// abbreviation is valid; use case http://www.google.com/search?q=movie%3A+movie+crash&sc=1&near=350+Lexington+Ave%2C+New+York%2C+NY&rl=1
// 0.3 2005-07-02 4pm Version tag 0.3 in iframe URL, so map frame can notify users to upgrade if their version is lower
// New links to show + hide the map, hidden map loads faster (doesn't hit vinq.com)
// New menu items to toggle whether map should be shown immediately
// Rewrite ; to , within lat;long points, for better matching
// 0.2 2005-06-30 4pm Added support for geo.position and GeoURL meta tags
// 0.1 2005-06-30 3am Initial version -- Mark Torrance www.marktorrance.com
