function theResult = lt(self, theItem)

% oct_netcdf/lt -- Redirect an item into self.
%  lt(self, theItem) redirects theItem, derived from
%   the ncitem class, into self, a oct_netcdf object.
%   If theItem is a cell-array, its elements are
%   processed one at a time in the order given.
%   When intending to copy more than one variable,
%   use a cell-array of variables for efficiency.
%   The returned value is the destination object
%   or list of objects, depending on context.
