reduceVrep

 reduce a V-representation to extreme points of convex hull

 Syntax: vrep = reduceVrep(vrep)

 This function wraps a cddlib function that reduces a set of points to the
   extreme points of their convex hull.

 Scaling of the input is important, because cddlib applies a fixed zero 
   tolerance. This tolerance is stored in the function zerotolCddlib 
   during initialization of this library (buildCddlib).
