/// Another interesting issue is that on Windows, the WebBrowser control by default is
/// effectively an IE7 browser, and I don't think you can easily change that without
/// changing registry settings. The lack of JSON parsing in IE7 triggers errors in google maps.
/// See https://code.google.com/p/gmaps-api-issues/issues/detail?id=9004 for the details.
/// Including the meta tag of <meta http-equiv="X-UA-Compatible" content="IE=edge"/>
/// fixes the problem, but we can't do that in the HTML that we set as InnerHtml in the
/// LoadHTML function, as the meta tag triggers a restart of the browser, so it
/// just reloads "about:blank", without the new innerHTML, and we get a blank browser.
/// Hence we set the browser type here.
/// Another way to get around this problem is to add JSON.Parse support available from
/// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON
/// into the HTML Script added when loading Google Maps
/// I am taking the belts-and-braces approach of doing both, primarily because the
/// meta tag, while probably the technically better" solution, sometimes doesn't work.
/// 10/8/17 - I've added yet another "fix" for this problem: the installer now writes a
/// registry key requesting that IE 11 be used for ApsimNG.exe (and for ApsimNG.vshost.exe,
/// so it also works when run from Visual Studio).
