#Older versions of Python don't support the print function while Python 3 doesn't
#like the print statement, so we use sys.stdout for the version check. After this
#check we can then use the print function in the remainder of this file. Currently
#in order to use logging, a lot of unnecessary code needs to be executed which could
#potentially render this version check useless. So logging won't be used here until
#there is a more efficient way to configure logging
