Added a class to parse JSON to objects and then reserialise them back to json again, but as objects on separate lines. This is how mapreduce requires it's input so that the files become splittable. Just uncomment the code in the main method to use it. Note that the filewriter method has been set to append, so you if you want to run the programme again, remember to delete the newly created files first, otherwise the data will be appended to the existing files.
Deleted jackson parsing files in the parse package.
