Added printing of row (along column) voxels for CIFTI Fiber Trajectory File that prints each Voxel's IJK, XYZ, and Row Index.
Added a method to CiftiXMLOld that places into DataFileContentInformation: every voxel IJK, XYZ, and Structure.  Use new method to print 'row' voxels for Cifti Fiber Trajectory File to assist with debugging trajectory data.
