Started building tests
Checking generator.createZip() for creation of an empty zip file
Added test for IllegalArgumentException on first argument in Generator.createZip()
Added JavaDoc comment for that last Test and fixed checkstyle warnings (seems I forgot to do that)
Added test for the second argument in Generator.createZip(). If that argument is null, an empty File should be created
Fixed Generator.createZip() so that that last test (checkSecondArgumentNull()) works
Changed pom.xml to the correct assignment (forgot that too)
Did Assignent 2 h) and added it as comment at the end of GeneratorTest
Changes in bonus assignment
Changed sysout and comment for tearDown()
Merged CheckZip branch
Deleted Assignment 2h) comment since it is not relevant to the program itself
