[Routing] "avoid-obstacles" algorithm

[Daniel Kastl]

Hi Iván,

That's probably a strength of pgRouting (http://pgrouting.postlbs.org)
because you store your network data in a database, so you can use SQL to
select as cost whatever you like and load just the data you need. With
other PostGIS functions you can for example exclude areas you like to
avoid or make them more "expensive".
