Empty lines between the Given/When/Then regions in tests

See for example http://stackoverflow.com/questions/1643933/given-when-then-example-with-nunit#1645721

When a test body is short, like in your case, I think the comments can be omitted.

So, rather than

```
[Test]
public void RotateAngle_Given27Degress_Returns64Degrees()
{
   //Arrange or Given
   var someAngleClass = new Angle();

   //Act or When
   var result = someAngleClass.Rotate(27);

   //Assert or Then
   Assert.That(result, Is.EqualTo(64));

}

```

one can use

```
[Test]
public void RotateAngle_Given27Degress_Returns64Degrees()
{
   var someAngleClass = new Angle();

   var result = someAngleClass.Rotate(27);

   Assert.That(result, Is.EqualTo(64));

}

```

without loosing in expressivity while wasting less space.
