Gradle integration, with 1 passing test and no artifact files in the repo

The Eclipse files (```.project```, ```.classpath``` and ```.settings```) have been removed.

The project files have been setup according to a default Maven/Gradle layout. ```JUnit v4``` is defined as a dependency, and will be downloaded from MavenCentral by Gradle.

In order to import the project in Eclipse

* Install ```Help/Eclise Marketplace``` ```Gradle Integration for Eclipse (4.4) 3.6.1 RELEASE``` ignoring the warnings.
* Import the project with ```File/Import```, select ```Gradle Project```, select the directory root
* click on ```Build Model```


From the console, 

```gradle build``` builds the jar
```gradle test``` to run tests.

You'll find one passing test, which you can run from Eclipse or from gradle.

There's only 1 ```.gitignore``` file.
