Stylistic convention

[albinahlback]

In order to have the same style as Julia, methods like getPos should be changed (if needed) to something like getpos.

I personally like camelCase but am not very dogmatic about it ... so happy to see PRs to change it if someone feels strongly about it.

But there are other functions with _ so yeah, your're right, we should probably change this to be consistent.

@aviks, what is your opinion on tab size and keeping a maximum of 80 chars on every line?
