The function is_cw_strongly_convex_2 determines if a given sequence of points defines a clockwiseoriented, stongly convex polygon. A set of points is said to be strongly convex if it consists of only extreme points (i.e., vertices of the convex hull).
#include <CGAL/convexity_check_2.h>
 

 
returns true, iff the point elements in [first,beyond) form a clockwiseoriented strongly convex polygon. 
The default traits class Default_traits is the kernel in which the type ForwardIterator::value_type is defined.
