[x3d-public] Setting up GitHub mirror of SourceForge SVN repository

[Michalis Kamburelis]

Hi,

Don asked me to write a document summarizing my plans. Here it is:

https://github.com/michaliskambi/x3d-tests/wiki/Mirror-SourceForge-SVN-repository-on-GitHub

I hope we can discuss it, and agree to do it :) The job itself is
quite easy, so once we get consensus "let's do this", I offer to do it
quickly.

Regards,
Michalis
