Remove composer.lock from git repository

[ek9]

I believe the composer.lock file should not be part of this repository. The reasons being:

1. The CI should always run against latest versions of the package. As that is what any new user installing the package will get. This will make sure that we see any kind of breaking due to version updates early and can update our version constraints in composer.json file accordingly.
2. composer.lock is a common source of conflicts when developing / doing PRs, thus it becomes problematic as you need to rebase a lot of PRs if this file is updated.
3. Generally it's ok to include composer.lock in projects, but as this is more of a library/tool that is fetched and used by other users, then composer.lock should not be included in the repository. (Read more @ http://stackoverflow.com/a/24247443 )

I've just realised this is gone already. Closing.
