examples no README

book page 35 the crow note:

All of the code for this example can be found on Github. Because Ruby is constantly changing, the README file should include the most up-to-date instructions on getting these code examples working.

Hey Doug, you're completely right. I'll get around to writing READMES for all of these.

For the most part running bundle install bundle exec rake will run all of the examples.

Sometimes there are rackup files meaning you can run rackup

@hexgnu Hi hexgnu, I've bundled successfully with libopencv-dev installed, but when I rackup the first example, here is an error message saying OpenCV was built without SURF support in function cvExtractSURF (OpenCV::CvStsNotImplemented).

I've searched for this, it seems that the SURF support is in a package libopencv-nonfree but I can't find it in Ubuntu 15.10.

Could you provide more details about running the examples and the environment?

Thanks!
