[Soc] TDSP implementation for pgRouting Weekly Report

[Stephen Woodbridge]

Hi Jay,

I would like to echo Daniel's kudos on your project. You have done an 
excellent job this summer. It has been a pleasure to work with and I 
hope you have learned a lot and had a similarly good experience. I know 
you have school work to go back but we would be happy to work with you 
on other projects that might interest you and benefit pgRouting.

Many thanks for all your efforts and looking forward to working with you 
in the future.

Best regards,
   -Steve
