Sylvain Pion 07e470978e We have 4 overloads of centroid() now working: 
centroid(begin, end)
centroid(begin, end, dim_tag)
centroid(begin, end, kernel)
centroid(begin, end, kernel, dim_tag)
 2008-04-15 15:58:11 +00:00
Sylvain Pion 4477a9d986 Updates after the new d-dim stuff changes. 2008-04-15 13:53:58 +00:00
Sylvain Pion 2389cdcc1e Dimension detecting stuff rewrite. 
There is now Ambiant_dimension and Feature_dimension.
The handling of the dynamic dimension case is now done by having
the di,ension tag as the first thing provided, with the integral
constant value available only when it makes sense (INT_MAX no longer needed).
 2008-04-13 12:38:48 +00:00
Sylvain Pion 02e543a294 Add Dimension<T, K> whose nested "value" is the dimension of the ambiant 
space.  A special constant CGAL::Dynamic_dimension (equal to INT_MAX)
indicates the case where the dimension is only known at run time.

Pierre Alliez 04826e29aa tests performed for points on a line in 2D 
Doc: added definitions, did many fixes.
IMPORTANT: sylvain: double-check the definitions, and precise the dimension and types available for each of your function.

important change: I suggest to rename the function bounding_box to axis_aligned_bounding_box (min case later you will hack on the general one).
