This functions are used in the whole code and are mandatory for the python3 support to work. In python2 case nothing is touched. * cmp_to_key: converts a cmp= into a key= function * decode_list: decodes each element of a list. This is needed if we have a mixed list with strings and bytes. * decode_it: Takes the input and checks if it is not a string. Then it uses chardet to get the encoding.
