[MAINT] Improve clarity, thumbnails, and fix mistakes in multivariate examples

[tsbinns]

Was double checking the documentation for mistakes when preparing the v0.7 release and noticed a few grammatical errors, spelling errors missed by codespell, and general poorly-worded parts of my examples.

There was also a very useful reference for the time-reversal in the Granger causality method which I forgot to include previously.

I also discovered the wonder of sphinx-gallery in-file config options and specified some nicer thumbnails for these examples.

Not sure what is going on with the diff of the CaCoh example. Locally this shows only a few lines being changed, not the entire file being rewritten:

append ?w=1 to the URL and GitHub will ignore whitespace changes. Probably line endings are changing; did you make these edits on Windows (or change your git config setting for core.autocrlf)?

Thanks for the suggestion! And yes, am using Windows.

Thanks @drammock. Followed the instructions so hopefully this doesn't happen again, although I don't see any normalised files for this branch...

you may need to make a trivial change to the CaCoh example, save, commit, and push again, for the line endings in the remote to get reset to unix-style

Unfortunately doesn't seem to be picked up.

Have just given it another go in #196 and there it works. Closing this.
