I have created the bare minimal working rss reader.
It has 2 parameters other than help. LIMIT and URL. i will include more as time progresses.
I need to remove logic from the global scope. i have done most of it but i want to use a class
for this,yet I dont know enough about them yet as I was ill on the date of the lecture and the powerpoint was complex for me at this stage
setuptools havent been made yet, Ill try to make them now
