Technique - ensuring single pointer usage

[alastc]

Initial creation of the technique, comment on this pull request, and preview on rawgit.com.

Alastair, thanks for putting this together.

The text seems to indicate that drag and drop must have an equivalent yet in other threads I thought we agreed that drag and drop did not need an alternative? What is our position? this technique should match.

Single is misspelled as "signle" in the test section.

Hi Jon,
Good point, that's now been transfered over as issue #403
We'll get resolution on that first.

Need to revisit with #403 resolution in mind

[alastc]

I've removed the direct drag & drop references, and added the common example I come across (carousels), diff of updates. (And moved the AT paragraph into the description so it doesn't get removed by the build process.)

However, from experience with other techniques this seems like a 'test the SC' sort of thing, rather than a specific technique.

Should this be converted to something like: "Adding buttons so that path-based gestures are not relied on"?

It is a little vague at the moment, that might help make it a specific techinque.

I think this one got combined with #760 and was approved today, so closing this. (Unless @detlevhfischer thinks otherwise?)

GitHub says there's another open PR that depends on the tech-ensuring-single-pointer branch, so can't delete despite it being closed
