Understand why multiple animation frames are running

[danielcompton]

We noticed multiple animation frames are often running, but it's not clear why. We should find an explanation for this, so that we can either fix it if it's a bug in re-frame-trace (somewhat likely), or explain it in the docs and help people avoid it.

I was able to reproduce the multiple animation frames running todomvc without re-frame-trace installed. There needs to be more investigation on why this happens, but I suspect that it's Reagent based, not an issue in re-frame-trace.
