Update for Apache Arrow 1.0.0

[shukryzablah]

I don't really know how different the 1.0.0 version is from the current version.

Is it possible to get an explanation of the steps you have to take in order to update this library to work with the new Apache Arrow version?

I've pushed up a makefile which invokes a script to regenerate the low level bindings, and left some light instruction. This gives you a chance to contribute new bindings should you like (but be sure the higher level code still works).

If not, I'll get to it at some point. I first need to update my distro's version of apache-arrow.

Thanks for reporting!

How can I know if the higher level code still works? Is running the existing tests and the readme example enough?
