Our football team finished the championship.
The result of each match look like "x:y".
Results of all matches are recorded in the collection.
For example: ["3:1", "2:2", "0:1", ...]
Write a function that takes such collection and counts the points of our team in
the championship. Rules for counting points for each match:
if x > y: 3 points
if x < y: 0 point
if x = y: 1 point
