D3 suggestion: rename "range" to "sequence"

[Tommi]

Renaming the concept of "range" to "sequence" would make our 
terminology more consistent with mathematics. It requires typing 
three more characters, but I think the gained consistency makes 
it worth it.

I know, not a current issue, but better bring it up now than when 
it's too late.
