[Potlatch-dev] Introducing Magic Roundabout tool

[Andy Allan]

Hi Steve,

Unfortunately it doesn't compile - I think you added a length()
function to Elastic.as but haven't added it in! Also, DrawWay.as#328
needs fixing since that doesn't compile either. Could you have a look
as soon as you get the chance - I'll hold off from uploading my
commits for the moment and just work on things locally.

(Also, best to avoid committing code with compiler warnings - there's
now some missing type declarations, class-scoped vars (I suspect you
want these instance scoped), duplicate variable declarations - give me
a shout if you're unsure or don't have time and I can sort them out
for you)

Cheers,
Andy
