    function out = vertcatCellContents(c)
% Helper that performs a vertcat on the contents of a cell array.
%
% This exists as removing a layer of cells is done in the evaluation tight
% loop and the input has a good chance of being scalar. Avoiding vertcat in
% these cases proves to be much faster.
