%OA2TR Convert O/A vectors to homogeneous transformation
%
% 	TR = OA2TR(O, A)
%
% Returns a homogeneous tranformation for the specified orientation and 
% approach vectors.  The rotation submatrix is formed from 3 vectors such that
% R = [N O A] and N = O x A.  
% The submatrix is guaranteed to be orthonormal so long as O and A are 
% not parallel.
