Maven

Hi,

WIth this change the slicer builds with maven. So dependencies are declared in the pom file and no longer included as jar files in the repository.

If you pull this, you may want to restore the first few lines of the README file. (I assumed you probably don't want to make this rather large change, so I adapted it to my fork.). Also the url in the root pom file points to my fork, you may want to adapt this and the groupId (I used my own domain here).

Best regards,
Holger.
