%
% SEQUENCE is a vector, MODE is a specification of how you want your output
% to be not sorted.
%
% Basically the same as unique, but returns the unique values either:
% "in order of appearance" - (MODE = 'first' for 'first occurrence')
% or
% "in order of disappearance" - (MODE = 'last' for 'last occurrence')
%
% MODE defaults to 'first'

if nargin == 1
mode = 'first';
