%CLOSEST Find closest points in N-dimensional space.
%
% K = CLOSEST(A, B) is the correspondence for N-dimensional point sets A (NxNA)
% and B (NxNB).  K (1 x NA) is such that the element J = K(I), that is, that 
% the I'th column of A is closest to the Jth column of B.
%
% [K,D1] = CLOSEST(A, B) as above and D1(I)=|A(I)-B(J)| is the distance of the
% closest point.
%
% [K,D1,D2] = CLOSEST(A, B) as above but also returns the distance to the
% second closest point.
