Add CI script

[jschueller]

This allows running tests automatically. Seems many fail atm.

[modelonrobinandersson]

@jschueller can you show what kind of errors you get? When I run the tests they all pass.

[jschueller]

Perhaps its a different sundials version ? Maybe we can merge this so we will see the exact error message.

[jschueller]

actually it is only 1 error:

@modelonrobinandersson which sundials version do you use ?

[modelonrobinandersson]

@modelonrobinandersson which sundials version do you use ? Sundials 2.7.0

[jschueller]

@modelonrobinandersson ok, indeed everything works with sundials 2.7

[jschueller]

@PeterMeisrimelModelon could you merge this one too ?

[PeterMeisrimelModelon]

We are currently looking into making the necessary setup on our side, but are in principle positive on merging this.

[jschueller]

do you have an internal ci server ?

[PeterMeisrimelModelon]

Yes, we do.

[jschueller]

so I guess it shouldnt clash with github actions continuous integration here, right ?

[jschueller]

ping @PeterMeisrimelModelon

[PeterMeisrimelModelon]

Unfortunately still waiting for an OK from our IT on this one, I want to merge this asap once we got it.

[PeterMeisrimelModelon]

Finally got this sorted out, apologies that this took so long.
