Feature branch II first commit : refactored

I have restarted the project and cleaned up the folder by removing the unnecessary test files and images. I also changed the full name property's name to the one suggested and no problems encountered yet on the site. Lecturer object now displays full name as opposed to ambiguous 'Lecturer object' in the site view. Tasks 1 and 2 have been tackled above the bare minimum and there is possible room for improvement. Please advise on any further changes needed. 
Have a look at https://www.python.org/dev/peps/pep-0008 (not in too much detail!). It is the Python style guide. Applicable here because after imports you need two blank lines.
