sum-of-multiples: Implemented issue #141

[Dog]

Implemented issue #141 which requested that sum_of_multiples use a function rather than a class.

I implemented the multiples as a list because it made it easier to differentiate them from the limit when looking at the test file. In the example I set the default multiples to None to avoid a python gotcha with mutable default arguments.

Is there an issue with this implementation?

I think this just slipped through the cracks. Thanks for pinging!

@sjakobi would you sanity-check this when you have a moment?

[sjakobi]

Sorry for the delay, @Dog!

I wanted to merge both your changes and #139 but it seemed complicated and at some point I forgot about it.

@kytrinyx: Do you see a way to merge both PRs and resolve the conflicts between them?

[kytrinyx]

I generally merge things locally when there are conflicts.

I would suggest merging #139 and then you can do this locally:

git checkout master && git fetch origin master && git reset --hard master && git fetch origin refs/pulls/139/head && git checkout -b Dog/sum-of-multiples FETCH_HEAD

which will make sure that you have a fresh master as well as a local branch with the pull request in it.

Then you can run git rebase master on the Dog/sum-of-multiples branch to resolve conflicts per usual. @Dog's commits will still be attributed to him, and you can merge onto master locally once the commits are resolved.

The other option is to merge one and ask the other author to rebase onto the new master and resolve commits :) I will generally go this route if I'm unsure of how I would resolve the conflicts.

[Dog]

No problem. I had a feeling if there was an issue someone would have commented. I'm still getting accustomed to working on Github though.

Thanks

This is closed by #149, I think. If I'm wrong, please reopen this!
