We don't use the `config/api.yml` file since commit c984e666f, and the
`.delete("\n").delete(" ")` in the code examples isn't necessary (we
should have probably added it in commit 56e42f209).
We're also changing the responses so there are no references to any
specific city.
We were getting many errors when trying to run them, from uninitialized
constant `HTTP` to undefined method `headers`.
We might move these examples to the documentation repository in the
future, but we need to look for possible side-effects first.
We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.
