found bug in checking for imports now checks results grid as well

[string,found] = object.pvs_check_for_imports_g(object.data.Grid2,{});

[string2,found2] = object.pvs_check_for_imports_g(object.data.Grid1,found);

% check for imports in the inputs field

hashtable = {{'sqrt', 'reals@sqrt'} {'sin', 'trig@trig_basic'} {'cos', 'trig@trig_basic'} {'tan', 'trig@trig_basic'}};

% check for imports in the results grid.

for i=1:size(object.data.Grid0.Cells,2)

    text = char(object.data.Grid0.Cells(i).result_text);

    vars = regexp(text,'([a-zA-Z][a-zA-Z0-9_]*)','match');

    for j=1:size(vars,2)

        if(exist(vars{j},'file')==2 && ~strcmp(vars{j},'otherwise'))

            %check if already imported file

            if (~any(ismember(found,vars{j})))

                string = [string 'IMPORTING ' vars{j} sprintf('\n')];

                found = [found vars{j}];

            end

        end

        for k=1:size(hashtable,2)

            if strcmp(vars{j},hashtable{k}(1))

                if (~any(ismember(found,vars{j})))

                string = [string 'IMPORTING ' char(hashtable{k}(2)) sprintf('\n')];

                found = [found vars{j}];

                end

            end    

        end

    end

end

    functions = regexp(char(object.data.function_inputs),hashtable{k}(1),'once')
