added README line and logging line to clarify location of service

Hi Guys!

After struggeling and puzzeling a little bit I've managed to get dcms running on my Mac. I've added a pointer line in the README and a console logging line to the server to help other beginners in the right direction. Also, this is my first pull request so it's a bit of a git tryout tutorial for me as well.

Was nice to snoop around the code and see it working on my own machine instead of peeking at declan's demo ;)

good luck with the project and greets,
Peter
