Issue #373: ANIm should not be symmetric

[baileythegreen]

With this PR, ANIm is no longer treated as symmetric. Comparisons between each pair of genomes are run in both directions; enforced sorting of output file names has been disabled; tests relying on this sorting are skipped; and documentation has been updated.

Closes #373.

tests relying on this sorting are skipped

What is the reason for retaining and skipping them? I would have thought deleting/removing the tests would be appropriate.

I wanted to think a bit about whether there might be a different use for it (there's really only one such test), or whether it might be usefully repurposed before completely removing it.
