Put OSCAT lib inside a submodule / other repo

[GISED-Link]

Hi and sorry for not folowing the default issue format.

First, thank you for hosting the OSCAT lib. This is a really good thing that at least someone have done this.

I'm only interested in the OSCAT lib and I will to contribute to it since the last changes have made ages ago. As I have seen in the OSCAT forum, here is the only active git repo for OSCAT. http://www.oscat.de/community/index.php/topic,4425.0.html

Please provide another repo for the OSCAT lib. If the lib is seperated, you can pin this repo (AixOCAT) to a specific commit/release of the future OSCAT repo so you can always be sure to work on a known state of the lib.

With the lib placed elsewhere we can also do continuous integration and unit testing of the lib, too!

By the way, there are quite a lot of open source things here and there, here are some examples: https://github.com/TcOpenGroup https://tcunit.org/
