Add links to new single pom sample project

[AlexDBlack]

A number of our users don't have sufficient experience with Maven to write their own pom.xml file from scratch, and the examples (multi-module maven project) is too complex.
Thus I've added this: https://github.com/deeplearning4j/dl4j-examples/tree/master/standalone-sample-project.
deeplearning4j/deeplearning4j-examples#668

Docs should be updated where appropriate to point users to that.

Can I suggest a different way of doing this? Provide Giter8 templates: https://github.com/foundweekends/giter8

[AlexDBlack]

We've (@raver119 and I) have also talked about building a simple website utility... the idea is you tick the dependencies you want, click "create project" and are given a zip (or pom.xml) or whatever back.

Links to the standalone projects should be enough.
Anything more can have negative returns: If users are unable to get this standalone project to work then there really is nothing (web utility, maven archetype, giter8 template, ...) that will help. It just adds utilities for us to maintain. and questions on gitter about the utilities to answer.
