% SETTOFFSET sets the 'toffset' property of the ao with tsdata
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: SETTOFFSET sets the 'toffset' property of the ao with tsdata
%
% CALL:        objs.setToffset(val);
%              objs.setToffset(plist('toffset', val));
%              objs = objs.setToffset(val);
%
% INPUTS:      objs: Can be a vector, matrix, list, or a mix of them.
%              val:  In seconds
%                 1. Single value e.g. [2]
%                      Each AO in objs get this value.
%                 2. Single value in a cell-array e.g. {12.1}
%                      Each AO in objs get this value.
%                 3. cell-array with the same number of values as in objs
%                    e.g. {7, 5, 12.2} and 3 AOs in objs
%                      Each AO in objs get its corresponding value from the
%                      cell-array
