function theResult = uigetdim(self)

% ncitem/uigetdim -- Get a NetCDF dimension via dialog.
%  uigetdim(self) returns one dimension associated with
%   self, an "ncitem" object, selected from a list-dialog.
%   The returned item is an "ncdim" object, or the
%   empty-matrix [] if no dimension is selected.
