[pgrouting-dev] Pushed new version of pgr_vidsToDMatrix() to develop

[Stephen Woodbridge]

Hi all,

I just pushed a new version of pgr_vidsToDMatrix() that is coded in C 
and about 3 times faster then the plpgsql version. I'll probably remove 
the plpgsql version at some point as this is better.

The function is based on kdijkstra and much of the performance is 
because I load the edges only and then run kdijkstra N times. There is 
still some room for improvement if someone with Boost experience want to 
try a build the graph once and then reuse that N times. My could builds 
the graph N time.
