TriangleValidator

This project provides a script that counts the number of valid triangles in a file, where

In a valid triangle, the sum of any two sides must be larger than the remaining side. For example, the "triangle" given above is impossible, because 5 + 10 is not larger than 25.

See: http://adventofcode.com/2016/day/3

See data/input.txt for an example of the file format.
