include efficiency

[rglides]

is there an efficiency/performance impact keeping includes within includes, or is it better practice generally to try to keep includes as close to 'top-level' (would that be the term?) as possible?

@rglides I think it can make it more confusing to keep track of files if you go more than two or three levels, but I don't think there is a performance penalty.

@d-healey Excellent, thanks David!
