Remove Tracker workaround

[devmotion]

Fixes #20 since the referenced issue is fixed (and Tracker is somewhat retired anyway and not tested anymore).

@tpapp do you remember why you wanted to use copy(x) instead of indexing into the provided vector?

[tpapp]

Yes. By default none of the as(Array, ...) transform share structure, so this should copy.

There is as(view, ...) for the special case.

I was wondering, isn't that already achieved by taking the subset x[index:...]? This already creates a separate array.

[tpapp]

Good point. Then I have no idea why I had copy.

Thanks for all the improvements. Should I tag a release or do you want to make more changes?

[tpapp]

lgtm, thanks!

I don't have any plans for additional PRs right now, I just happened to do some TransformVariables-related work this morning 😄 So it's probably time for a new release.
