What problem does this PR solve?

This PR configures the Maven assembly plugin to build a single fat JAR for each subproject. Each fat JAR follows the naming scheme ${pattern}-${version}-SNAPSHOT.jar.
After the Maven Assembly Plugin has been executed, the resulting artifact can be executed as follows:

$ mvn clean package -DskipTests=true
