matlab atlinopt4 check on 6d is disabled

[oscarxblanco]

Dear all,

the function atlinopt4 does the calculation without checking if the pass methods are 6d or 4d. The obsolete function check_radiation is commented and was not replaced.

at/atmat/atphysics/LinearOptics/atlinopt4.m

Line 96 in 5028aaf

%check_radiation(ring,false);

This is a problem because the closed orbit changes, and it produces an effect on the optics.
I propose to set a warning if the lattice is 6d.
