The zeros/roots of the spherical Hankel function of the second kind

[feima0011]

https://github.com/sfstoolbox/sfs-matlab/blob/master/SFS_general/sphbesselh_zeros.m
find zero and root for the spherical Hankel function of the first kind.

However:
% The zeros/roots of the spherical Hankel function of the second kind
% can be obtained based on the following relationship.
% suppose z = x + iy is a zero for the spherical Hankel function of the first kind.
% then z = -ix + y, and z = -ix -y are zeros for the the spherical Hankel function of the second kind.

Please add this to the https://github.com/sfstoolbox/sfs-matlab/blob/master/SFS_general/sphbesselh_zeros.m

Thanks for commenting.
Do you propose to add the comment to the docstring of sphbesselh_zeros or where do you would expect it?

I want to add to the comments at the start of the file
https://github.com/sfstoolbox/sfs-matlab/blob/master/SFS_general/sphbesselh_zeros.m

but I do not have the right to make the modifications.
