** THIS IS A TASK IN ERLANG PROGRAMMING LANGUAGE

Write an Erlang function named zip that takes two parameters, both lists. The function should return a single list made by interleaving the contents of both lists. For example, if we called the function zip( [1,2,3,4], [5,6,7,8] ) we should get [1,5,2,6,3,7,4,8]. If the lists are not the same length, just add the extra at the end. For example, zip( [1,2,3,4,5], [a,b,c] ) should return [1,a,2,b,3,c,4,5].
