% SETDELAY sets the 'delay' property of the pzmodel object.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: SETDELAY sets the 'delay' property of the pzmodel object.
%
% CALL:        objs.setDelay(val);
%              objs.setDelay(val1, val2);
%              objs.setDelay(plist('delay', val));
%              objs = objs.setDelay(val);
%
% INPUTS:      objs: Can be a vector, matrix, list, or a mix of them.
%              val:  numeric value in seconds
%                 1. Single vector e.g. 9
%                      Each pzmodel object in objs get this value.
%                 2. Single vector in a cell-array e.g. {7}
%                      Each pzmodel object in objs get this value.
%                 3. cell-array with the same number of vectors as in objs
%                    e.g. {12, 2, 5} and 3 pzmodel object in objs
%                      Each pzmodel object in objs get its corresponding
%                      value from the cell-array
