A model for this must provide:

template <class ForwardIterator>
Kernel::Point_d fo ( ForwardIterator first , ForwardIterator last )
returns the center of the sphere spanned by the points in A = tuple [first,last).
Precondition: A contains d+1 affinely independent points of dimension d.
Requirement: The value type of ForwardIterator is Kernel::Point_d.
