Publish the package at spark-packages.org

Make this into a Spark package and publish at spark-packages.org so it's easy to use from any Spark installation. Instructions:

Third-party packages for Apache Spark should take care to respect the trademark in "Apache Spark" and its logo. Please refer to Apache Trademark Policy and Apache Trademark FAQs for comprehensive and authoritative guidance on proper usage of ASF trademarks. Names that do not include "Spark" at all have no potential trademark issue with the Spark project. This is recommended. Names like "Spark BigCoProduct" are not OK, as are names including "Spark" in general. The above links, however, describe some exceptions, like for names such as "BigCoProduct, powered by Apache Spark" or "BigCoProduct for Apache Spark". It is common practice to create software identifiers (Maven coordinates, module names, etc.) like "spark-foo". These are permitted. Nominative use of trademarks in descriptions is also always allowed, as in "BigCoProduct is a widget for Apache Spark".

Besides a proper name, a package needs to meet the following requirements to be included in Spark Packages:

Its content must be hosted by GitHub in a public repo under the owner's account. The repo name must match the package name. The master branch of the repo must contain "README.md" and "LICENSE". An example package that meets those requirements can be found at https://github.com/databricks/spark-avro.
