Demo

When trying out the golang bindings, I found it couldn't build the tool because the API has changed since it's last been updated. I added the new parts of the API so it does build. I also updated the example and README to match the updated API.

Steps to Reproduce

If you follow the steps in the readme and try to make the bindings, you get an error because the C-api has changed.

Notes

I'd like to work more on the bindings. The tests need to be updated, and the API actually has new features that aren't implemented in golang yet that I'd like to add.
