[pgrouting-dev] [pgRouting/pgrouting] 2d7e98: update some functions

[Razequl Islam]

Hi Steve,
Thanks for the information. As I have lost some days, I am working hard to
make that up. I am still having some issues with the test environment. I am
fixing those and hopefully this will be completed within two-three days. I
will then invite you to run the program using some sample files and have a
feel of that. Once it is done, I will start to write codes for taking input
from database and feed it to the algorithm. There are some design issues
and so I will need help from you and Daniel. I have started looking at the
codes for TSP and DARP as they have similarity with VRP. As for push_back
issue, I will follow your suggestion. May be we implement the copy
constructor of the class as push_back calls the copy constructor.
