+====== Vector2 ======
+Vector2 consists two floats, ''x'' and ''y''.
+Similar to Matrices, Vectors also have two methods of accessing their variables.
+Namely, you can access them directly, or using the ''[]'' operator, similar to an array.
+The following example uses both methods:
+<code c>
+float Vector2::Dot(const Vector2& other) const {
+	return asArray[0] * other.x + asArray[1] * other.y;
+}
+</code>
+Vector2 also features the following utility functions:
+  * ''Dot''
+  * ''Magnitude''
+  * ''MagnitudeFast'', which omits the square root function call, providing a very helpful speedboost.
+  * ''Distance''
+  * ''Normalize''
+  * ''Angle'', returns the angle between this and another Vector2
+The following utility functions return *new* Vector2 objects:
+  * ''Project''
+  * ''Perpendicular''
+  * ''Reflection''
+  * ''Clamp'', clamps the vector between a given min and a max.
