Details:

I would like to contribute the below missing functions to octave-image

- niftiread
- niftiinfo
- niftiwrite

The current version can be found at 
https://github.com/fangq/jnifti/tree/master/lib/octave

and are also attached in this thread. They can handle .nii, .nii.gz,
.hdr/.img, .hdr.gz/.img.gz files. The input/output of these function smatch
MATLAB's versions.

The newly drafted functions do require a set of helper functions to fully
function:

- To read/write un-compressed NIfTI-1/2 (.nii) files, it minimally needs the
JNIfTI toolbox at https://github.com/fangq/jnifti/tree/master/lib/matlab

- To read/write gzip-compressed NIfTI-1/2, it needs the ZMat toolbox at
http://github.com/fangq/zmat

- To convert the NIfTI data to the more portable version for easy
manipulation, i.e. the JNIfTI format, it needs the JSONLab toolbox at
http://github.com/fangq/jsonlab

I've tested these functions on both Octave 4.2 and 5.1, using the NIfTI-1/2
sample data provided at

https://nifti.nimh.nih.gov/nifti-1/data

all works nicely.

I am wondering if anyone is interested in reviewing these functions and give
some suggestions? first time contributor to Octave.
