Modified Clock description and added first comments on the Vector2 and Vector3 classes. Though I have to comment the comparison methods of the vector classes too.

/* SFML::Vector2 is a simple class that defines a mathematical vector with two coordinates (x and y).
*
* It can be used to represent anything that has two dimensions: a size, a point, a velocity, etc.
*
* This class differs from the C++ version. It will accept any value that is Numeric and both x and y must be of the same class.
*
* v1 = SFML::Vector2.new(16.5, 24.0)
* v1.x = 18.2
* y = v1.y
*
* v2 = v1 * v1;
* v3 = SFML::Vector2.new
* v3 = v1 + v2
*
* different = (v2 != v3);
