Created NUnit test methods for api examples

The examples are for the old API and don't work for the new one. Next
thing to do will be to make them work with the current API.
Tests compile now, but generate exceptions.

And there is pretty much no assertions yet.
Now using settings to determine api url and credentials.
Deleted classes with RequestData postfix
Added packages to .gitignore
Merge branch 'development' of https://github.com/co-sky-developers/.net-sdk into development
