[OSM-dev] Tool to simplify ways

Looks promising but it has a disadvantage: I can't use it in a batch 
process
And I don't understand why it doesn't delete some nodes. I've got the 
threshhold real high (1000m) and it sometimes doesn't remove a node that 
is almost dead straight with its two adjacent nodes.

Maarten
