Bring the power of master to v2
Okay so much success

I have figured out how to write to mongodb and read from it (both!) and
started working on adapting some of the code i wrote to do a basic
version of that. Hope to get more soon.
Functional display of database

Now the database results can be seen. Look for when the response.end()
is called.
Sleep is an easy solution

We found out how to use sleep to fix our problems of response.end() -
not elegant but it works. Time to start looking at how to truly work
with asynchronous applications.
