Add more examples to documentation

[tcbrindle]

While the reference documentation is comprehensive, it would be very handy to have some high-level examples of what the library can do and why I would want to use it.

For example, Howard Hinnant's excellent date library has a page of "examples and recipes" available in its wiki.

I agree this would be nice to have. The only examples I've posted so far are those in the overview section of the readme (https://github.com/tahonermann/text_view#overview). Do you have any suggestions for good examples? The current feature set is pretty limited (I plan to start working on new features in the next couple of weeks), and I have struggled to come up with interesting examples because of that. Any chance you would be interested in drafting some wiki pages?

Hi Tristan. I finally got around to throwing together a few wiki pages loosely following Howard's work as you suggested. Does this match what you had in mind? Any suggestions for improving it would be welcome.
