Update readme with openresty examples

[artagel]

With OpenResty, we can offload all authorization functions from vouch and keep it lean and focused. I think we should provide a couple of common examples to provide to users.
The readme is starting to get busy... perhaps it is time for a wiki, and we can add it there instead?

I'm going to truncate the examples a bit so it's not redundant with the existing Nginx example

would you care to host a gist of the original which we would link to in the README?

@artagel I made some adjustments when I merged, please do take a look and let me know what you think

[artagel]

I think it all looks good.

Did that gist ever get created? I tried pasting the lua snippets into my nginx config and it's not working; I don't see how it's calling vouch at all so I suspect I'm missing some important context which the full config would make clear.

I have some better formatted examples I’ll try to push this weekend.
You need to ensure you use openresty, which is nginx compiled with lua, otherwise nothing will work :)

#137 Has the examples I was talking about.

[bjornicus]

Yes, definitely using openresty :)

Thanks, these full examples are exactly I was hoping existed.
