[mboisnard]

Prepare step for #3

TODO:

• Create repository on Sonatype (Jira project creation)
• Add GPG maven plugin to sign jar
• Add settings.xml file and configure Travis CI to replace variables. Example:

<server>
     <id>ossrh</id>
     <username>$OSS_USERNAME</username>
     <password>$OSS_PASSWORD</password>
</server>

• Configure maven release step

Hi, thank you for that. We have a process in place to publish on maven central. We just have to check if what you did works for us, so it may take some time...
