+
+Some convenient functions provided for AABB.
+
+**Definition of aabb:**
+
+cglm defines an aabb as a two dimensional array of vec2's.
+The first element is the **min** point and the second one is the **max** point.
+If you have another type e.g. struct or even another representation then you must
+convert it before and after calling a cglm aabb2d function.
