Finally removed the usernames properly. Once the files have had the
usernames removed from the file, we store them into a temp folder
'tempFiles/' from there we now work on the tempFiles as opposed to the
original, thus reducing the total wordcount whilst working the with data
we are interested in. Finally i have put inplace a new global comms
class called TearDown at the moment this simply removes all the files in
the temp directory however i think this could be useful later on to
ensure i am writing optimal code.
