TypeError: search() missing 1 required positional argument: 'string'

First error is this thing above, that the input has to be passed to the re.search as the second argument. Second error is that the regex needs to capture more than one digit on the version numbers with a + after each [0-9].

This issue should be fixed by the last version of PySwip.
