Review request, Initial source code

["Edward J. Yoon" <ed...@apache.org>]

Hi forks,

I've created maven-based project and imported ANN source code from
Hama ML package, including main BSP-based ANN program, its unit tests
and examples.

To build the project, you can use following command: $ mvn clean install

In my local computer, everything looks fine to me. Please review
HORN-3. Again, this legacy code is data-parallel only.

If there's no objections/opinions, I'll commit it within 3 days.

Thanks!
