[New software] openBmap logger (GSM positioning)

[onen.om at free.fr]

For the moment our position is:

We log the cell ids we get connected to.

We do not log the neighbour cells. The reason is: if we are far from the cells,
we will (maybe, this needs experimentation to my point of view) see the cells
even very far. I fear that it would stretch the areas, and thus decrease the
precision, nullifying the benefit of recording those additional cells.

But, my idea, is to use the neighbour cells, to detect the overlapping region
among areas of cells I currently see, to improve the precision.

Any comments?
