Add LGTM code quality badges

[xcorail]

Hi there!

I thought you might be interested in adding these LGTM code quality badges to your project. They indicate how you care about code quality and encourage your future contributors to do the same.
To get an idea of the analyses reflected by these grades, check the alerts discovered by LGTM.

N.B.: I am on the team behind LGTM.com, I'd appreciate your feedback on this initiative, whether you're interested or not, if you find time to drop me a line. Thanks.

Hi @xcorail, thanks for the PR!

LGTM looks like a great product, but we generally prefer to avoid having too many badges in our libraries' respective READMEs, so I'm going to close this without merging.

OOC, did you build your own code analysis engine, or is it built upon existing tools (e.g. Error Prone)?

Yes, our code analysis engine is proprietary, not built upon or not aggregating results from other tools.
But the analysis themselves, that our engine runs, are open source at https://github.com/Semmle/ql. This way, our customers contributions are given back to the community (example)

I understand your point. Note that anyways, the LGTM alerts will be always available for you, as this service is and will remain free for open source projects, so feel free to use it, and ask for help or give feedback.
By default, your repo is tentatively polled once a day, and all commits are analyzed, most recent first. But if you activate automated code review, any pull request will be analyzed immediately, and the results are reported directly in the PR comments. This is also free and a one click operation.

Cheers

Cool, thanks for the quick reply. I'm already in the process of writing a few PRs to fix alerts reported by LGTM, including an actual error in our Python library! 😱

Looking forward to seeing you add support for Ruby, PHP and Go :)

Cool! I am glad you found it helpful 😃
Again, I can only advise to activate pull request integration to make sure that this error (or any other) never reaches your master again.

Looking forward to seeing you add support for Ruby, PHP and Go :)

Go is next on our list! Keep an eye on the community announcements!
