tox configuration and usage examples

• Basic usage
  • a simple tox.ini / default environments
  • specifying a platform
  • whitelisting non-virtualenv commands
  • depending on requirements.txt or defining constraints
  • using a different default PyPI url
  • installing dependencies from multiple PyPI servers
  • further customizing installation
  • forcing re-creation of virtual environments
  • passing down environment variables
  • setting environment variables
  • special handling of PYTHONHASHSEED
  • Integration with “setup.py test” command
  • Ignoring a command exit code
  • Compressing dependency matrix
  • Prevent symbolic links in virtualenv
• pytest and tox
  • Basic example
  • Extended example: change dir before test and use per-virtualenv tempdir
  • Using multiple CPUs for test runs
  • Known Issues and limitations
