lemme precise this a bit....
for now, freertr stores the ribs in a sorted-synced 2 level hierarchical array
http://sources.freertr.org/src/net/freertr/tab/tabGenV2.java
it gives us good read and write times on random accesses
(both initial floodong and bigger reconverges need this)
in the same dir you can find the tire and the tabRoute too
