Allow the composition of several conf files

[kdund]

It would be really nice for future run combinations etc. if we can make a statistical model from several configs each coding for a likelihood term!
So you would have one file each for SR0, SR1 etc. (once you fix each of them)

Compelling idea @kdund ! 😊 What should be done though if say you want to have shared parameters across likelihood terms? Also, one would probably need some hierarchy in the sense of overriding duplicate information, right?

[kdund]

Shared parameters should be checked for being equal and then accepted, I think.

[hammannr]

Sounds reasonable!
