Title: Style and idiomatic simplifications.

Use range and make other code shorter and more idiomatic.

Should not change behaviour in any way.

Also documented (some) controls in Readme, this probably belongs in a different branch/pull-request but I'm a git/github newbie and at the moment I spend more time swearing at it than getting anything working.
