D4M Java support in maven repository

[David Medinets]

Y'all may recall that I did some work with D4M over the summer. I've
moved the D4M TableManager into its own project
(https://github.com/medined/d4m) and deployed it to the Central
Repository. It can be downloaded via Maven at:

        <dependency>
            <groupId>com.codebits</groupId>
            <artifactId>d4m</artifactId>
            <version>1.0.0</version>
            <type>jar</type>
        </dependency>
