Compare coala+gitmate with danger

[jayvdb]

danger includes process and code quality automation, integrated with GitHub and other code repository systems.

An example of process automation is requiring PR authors join the organisation.

coala only provides code quality automation with the addition of git commit message checking.
gitmate adds GitHub integration.

coala+gitmate lacks process automation, and is not especially interested in pursuing that goal.

However coala+gitmate does expect to be better at code quality automation than danger.
A comparison on this wiki would be useful to ensure that coala developers acknowledge where open source competitors in this space, like dangar, are out performing coala.
