Separate samples from sources and from application

Hello!
I want to help write some unit tests and simplify complexity of the code.

But it seems that a lot of stuff here that should be in other place:

• Samples: seems that they should be in separate repo called swagger-codegen-samples and simply use latest release of CLI-interface to build new versions.
• Swagger-generator: think it should be in repo called swagger-generator and contains modules:
  • swagger-web-app (with content of current module swagger-generator - is it same as in repo swagger-generator?)
  • swagger-cli (with content of current class Codegen) (done in #547)

Also, think repo swagger-parser should be in this repo, because of parsing schema with classes from swagger-parser repo only used to generate some kind of code. (answered)

Also, is there any doc of how to contribute to project? (answered)

Start by reviewing the repository’s module layout and the referenced modules/swagger-codegen/src/main/java/com/wordnik/swagger/codegen/Codegen.java class, then compare the current samples and swagger-generator contents with the proposed repository split. Confirm the intended boundaries with maintainers before changing anything; done would mean an agreed separation plan, since several points are already marked answered or done.
