Load local .kml files into the plug-in via ActiveX

Usage:

1) To make the example work add the page to the "trusted sites" zone in Internet Explorer.
2) Change the security setting for "initialize and script activex controls not marked safe for scripting" in "trusted sites" from "disable" to "prompt"
3) Click on the "Browse" button and select a kml file on your machine (e.g. C:\test.kml)
4) Click the "load kml" button.
5) When prompted click "yes" in the confirmation dialogue to allow the interaction.

Notes:

1) This example will only work in Internet Explorer as it uses ActiveXObject("Scripting.FileSystemObject")
2) There may be additional security settings to configure if the "trusted sites" zone does not have the default settings on your machine.
