Made node checking code more readable
Added express - some other funkier alternatives but express seems a solid start
Refactor to use express
Use app for consistency in tests rather than server
Turns out we can have a node version in package.json so its in there as well
Move to using static instead of test as may want more sophisticated dir structure later
Start getting the tests working serving static resources
Finish fixing the test that shows a file can be served
Testing callback is called is now a concern of express or will show up clearly in other tests so removed that test
The test for port numberage is probably not required either
Lets handle defaults for the args to start and stop
Fix the test so the data is asserted on properly - sloppy me when I refactored didnt changed it back to appending to chunk
