#6 Generated code in repository

[Wesley J. Landaker]

The repository appears to contain tons of source code that is generated. Most of this seems to be from Xtext.

1. Generated code is redundant, obscures the true source material, makes VCS history hard to comprehend and in effect generally serving as a sort of anti-documentation.
2. Having generated code in the repository makes development more fragile, as it does not discourage editing of generated code.
3. The saving of generated code implies that our build toolchain is either not automated, or not using open tools, either of which is problematic.
4. Except in specific exceptional situations, generated code is not appropriate in the VCS of an open-source project.
