SnirfClass now imports stim values of >0, -1, and -2 from nirs s matrix....

                t        = varargin{2};

                CondName = varargin{3};

                obj.name = CondName;

                k = s>0;

                obj.data = [t(k), 5*ones(length(t(k)),1), ones(length(t(k)),1)];

                k = s>0 | s==-1 | s==-2;  % Include stim marks with these values

                obj.data = [t(k), 5*ones(length(t(k)),1), s(k)];

            elseif nargin==0

                obj.name = '';

                obj.data = [];
