% SETY sets the 'y' property of the ao.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: SETY sets the 'y' property of the ao.
%
% CALL:        objs.setY(val);
%              objs.setY(val1, val2);
%              objs.setY(plist('y', val));
%              objs = objs.setY(val);
%
% INPUTS:      objs: Can be a vector, matrix, list, or a mix of them.
%              val:
%                 1. Single vector e.g. [1 2 3]
%                      Each AO in objs get this value.
%                 2. Single vector in a cell-array e.g. {[1 2 3]}
%                      Each AO in objs get this value.
%                 3. cell-array with the same number of vectors as in objs
%                    e.g. {[6 5 4], 5, [1 2 3]} and 3 AOs in objs
%                      Each AO in objs get its corresponding value from the
%                      cell-array
