Address issue #99

[lafita]

There is some error related to source.rcsb.org - I will have a look and fix tests using the website.

Nice, thanks @lafita

As you noted all access to source.rcsb.org should be discontinued as soon as possible. We are going to be shutting down the service soon. See the related PR in biojava: biojava/biojava#882

[lafita]

Thanks @josemduarte

Would this be fixed by updating to the next BioJava release?
SCOP identifiers are still available through the StructureIdentifier interface right?

That should do it. I hope it doesn't take too long for the next release to come.

Yes, the Berkeley provider is available but it is slow to initialise.

Ok, in that case I am going to merge this and we can fix the test issues (unrelated to this PR) when we have a new BioJava version.

Nice addition. It's good to see you're still using the tool!

[josemduarte]

@lafita regarding new BioJava version and the code I'm removing in biojava/biojava#882, it'd be a good idea to build this project using that biojava branch's snapshot and see if everything is alright. That is to confirm I didn't remove any needed functionality.

[josemduarte]

@lafita I've tried with biojava with the PR branch biojava/biojava#882 and the project built correctly including tests.

[lafita]

Thanks @josemduarte I am merging it then.
