Versionize xml

[maxnoe]

Now that FACT-Tools can access it's own version in code, we could add a class, that checks the version and exits if it does not fit, like this:

<fact.RequireVersion version="1.0.0" />

• XMLs used for thesis and publications state the FACT-Tools version that was used
• Results become more reproducible

What do you think?

What would be the correct thing to use in streams, as it should raise the error as early as possible?
StatefulProcessors init method? A Service?

[tarrox]

Using a Service should be the fastes as the services should get initialized before the processors. Also having the RequireVersion together with the variables and all, makes more sense as everyone is doing it that way (all other software). In addition this could be the first definition in the xml which is nice.
