[mkgmap-dev] new branch NOD127

Hi all,

I've created a new branch NOD127 :

This is used to test the latest findings regarding the NOD file format.
Most of it is understood now, thanks to Steve and his display tool :-) 

Changes in r3086 compared to trunk r3081:
- nodes are grouped by classes and additional arcs are written to connect
nodes. This seems to improve routing, at least it is much closer to what
real maps contain.
- avoid roundabouts works in Basecamp (only with "shorter distance")
- avoid toll roads works as expected, is trunk it has to be switched on
to allow routing on major roads 

A few open questions remain at this point:
- the carpool bit seems to have no effect, it is likely that there is a bit
in the NOD header that has to be switched on or off to change that,
but we don't know where.
- some original maps contain extra info for route restrctions, we don't know
yet what they mean.
