Summary	0007485: itkNiftiImageIO saves tensors in non-standard way
Description	Nifti 1.1 supports the SYMMATRIX intent code for the saving of symmetric matrices. The format as described in http://godzilla.kennedykrieger.org/sw/niftilib/group__NIFTI1__INTENT__CODES.html [^] , is lower triangular. itk uses upper triangular for it's internal storage and then uses the Vector intent code and saves the tensors in upper triangular order. This makes the nifti files incompatible with other software such as afni/medInria etc.
Steps To Reproduce
Additional Information	I'm attaching an edited 3.6 itkNiftiImageIO.cxx file that I believe addresses the issue although it is specific for the tensor class not for the itkSymmetricSecondRankTensor class
Tags	No tags attached.
