%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.
