rri_orient_ui.m

%  Return orientation of the current image:
%	orient is orientation 1x3 matrix, in that:
%	Three elements represent: [x y z]
%	Element value:	1 - Left to Right; 2 - Posterior to Anterior;
%			3 - Inferior to Superior; 4 - Right to Left;
%			5 - Anterior to Posterior; 6 - Superior to Inferior;
%  e.g.:
%	Standard RAS Orientation:	[1 2 3]
%	Standard RHOS Orientation:	[2 4 3]
