Introduce latexmkrc
Solves #5
Introducing a latexmk file allows it to move all style files into the .style folder. This removes 5 files from the root folder. And due to writing all compiled files to build folder also the temp files do not pollute the root. Also, now it is clear how to compile the template as the user just has to call latexmk in the root folder. And we do not have to have a ctan package or additional pachage to be installed.
