[jboss-jira] [JBoss JIRA] (DROOLS-4291) ModelWriter: refactor to smaller classes

ModelWriter: refactor to smaller classes ---------------------------------------- Key: DROOLS-4291 URL: https://issues.jboss.org/browse/DROOLS-4291 Project: Drools Issue Type: Enhancement Reporter: Edoardo Vacchi Assignee: Edoardo Vacchi Priority: Major Labels: drools-core ModelWriter performs most of the logic translating PackageModel into source files; then it writes the result to a virtual FS. This makes it harder to reuse common source-to-file logic. In this PR we refactor each part of the PackageModel-to-individual-source-files into separate classes, taking each one single component.
