% This function loads the question files and returns them in a cell
% array. The first column is the question identifier

% input:
%   inputFile   - name of the file
%
% output:
%   qIds        - question IDs, nx1 cell array
%   options     - options following the question ID. It is an nx1 cell array which contains
%                 the available options as another cell array in each line
