Better selector documentation?

[facelessuser]

It isn't bad, but it very brief. It more just says, hey you could use these with a brief example without much context. I don't think I need to dedicate a page to each selector, but maybe it would be nice to have each selector have a section that describes the selector in more detail and provides an example with HTML and Soup Sieve parsing it.

It'd be a lot of work, but if I don't get anymore Soup Sieve bugs, I could take my time on it. There probably aren't many more features to add per se. There are some selectors in the backlog, but I can't/am not implementing them right now.
