Remove examples/tiny.html?

[RyanGlScott]

Back in 2011, a tiny.html file was checked in. However, it has gone completely unchanged since then, and once #229 lands, it will be out of date with respect to the way criterion plots data. I'd consider regenerating tiny.html, but I can't even find the source code that created it! My best guess is that tiny.html was created from a one-off criterion program that has since been lost to the sands of time.

I suppose we could consider keeping tiny.html around for the sake of being an example criterion HTML report, but there are already examples in the www/ directory that serve the same purpose. Better yet, the examples in www/ correspond to actual, version-controlled examples, so they are actually maintainable. In light of this, I don't see much of a reason to keep tiny.html around. I propose just ripping it out.
