%SET    Set method for map entity object.%   E = SET(E,'PropertyName',PropertyValue) sets the value of the%   specified property for the map entity object E.%%   Note that the assignment to the output E is necessary since %   Matlab does not support passing arguments by reference. Hence%   the set method actually operates on a copy of the object.%%   SET(E) displays all property names and their possible values%   for the map entity object E.%%   Examples:%      e = set(e,'Id',201);% %   See also ENTITY/GET.% v.1.0, K.O.
