Put Noora behind a layer

[albertodebortoli]

Pull Request Title

#11 created a mock for Noorable to avoid printing when running tests. This proved to not be enough as the Noorable's format method returns a string that is eventually used by the print method, resulting in empty logs.

This PR puts Noora behind a layer (Printer) and the tests now use the corresponding mock (PrinterMock) to avoid printing anything at all to the console, achieving the original goal of the previous PR.
