Eclipse Papyrus 3.0 (Oxygen)

Papyrus 3.0 makes changes on the following topics: 

• Improve the user experience and usability (notably ergonomics, stability and performance). 
• Homogenize and improve DSML-related mechanisms (including customizability and extensibility). 
• Add new modeling and design facilities. 

In addition, some important architecture changes have been done for Papyrus 3.0:

• Introduction of a 'Papyrus for Toolsmiths' feature to regroup the Papyrus DSML-related mechanisms. 
• Better structuring of tests to be aligned with the architecture of Papyrus and to group them in consistent suites. 
• Purge Papyrus main Git repository from incubation work.
