This adds an extents<N> class which stores an array of n-dimensional extent values. This can be used to represent an ND-range for launching an OpenCL kernel or for storing the size/shape of a 2D/3D image. Also adds a variadic dim() function which provides a concise syntax for creating extents<N> objects.
