Homework 4

Triangle Typer App with checks that the inputs are integers and the
triangles are scalene, isoceles and equilateral.

Also added checks / code to check that integer input is actually a
triangle.

Want to add other parameters to the TriangleTypeCalculator and the test,
but have questions before I move forward.
