function seq = ContoursUnleaveSequence(sesinfo)
%ContoursUnleaveSequence	Converts trial sequence into stimulus conditions
%	SEQ = ContoursUnleaveSequence(SESINFO) converts the stimulus
%	trial sequence (SESINFO returned from ContoursReadIniFile) 
%	into the stimlus conditions used in the experiment. 
%	SEQ has the following format:
%		SEQ.contour(i).repetition(j)
