The ObjectMapper does the actual parsing of the JSON input.
Running this example produces the following output:
Software: robinparse (1.2.3) by [Robin Smythe, Jon Jenz, Jan Ardann]
Of course there are cases where the mapping gets more involved; for this purpose, Jack-
son provides a set of annotations to control the mapping. But the default mapping is
pretty good!
