[pgrouting-users] Rewrite of one of the TSP functions, updated tests and docs, closing ...

[Stephen Woodbridge]

Hi All,

If you are interested in TSP functions, I just made some big changes. 
Look at issues #127 and #156 for details.

I have replaced one function with plpgsql functions, updated the 
documentation and test. This probably need some testing and reviewing.

Feedback welcome.

Thanks,
