Created an example and some changes to .cls

Changed the footer because page number not visible. Changed åäö to \" ,\aa , \"o in the .cls less need for troubleshooting in the .cls file because i had some trouble with the encoding. Made an example file so that a LaTex beginner have something to start from, it might not be perfect but it is a beginning. Added *.swp in .gitingnore. There is now an .pdf in the repo of the example, I like to get an overview before I start to use a repo.
