Problem : Collinearity testing 

Write a function collinear () that takes a list of pairs (tuples) as an argument, where each pair again represents a point on a plane. Your function should return True only if all points in the list are collinear, and False otherwise. If the list has less than three points (including none), you should trivially return True3.

For full credit, your answer in Problem lb should reuse your function from Problem la.

[Hint: If there are n points in the input list, it is sufficient that you check II - 2 appropriately chosen triples of points (there are several ways to choose which triples).]
