t3f.round() does not support epsilon

As opposed to TT-Toolbox and TTPY package, round() with a given epsilon, does not actually lead to a reduction of the rank for a function it is supposed to work...

amen_solve2 fails to converge, as opposed to its ttpy counterpart

So Ivan believes that it's a distinctive bug in MATLAB version so on the same matrix, with the same inputs: x=amen_solve2(A,b,tol,'max_full_size',15000,'kickrank',10,'x0',b,'nswp',15,... 'resid_damp',1 ,'rmax',100); ttpy amen_solve: swp=1, max_dx= 1.999E+00, max_res= 1.999E+00,...

on a cylinder surface Max curvature can be around 0 while Min curvature will be like 2.5 on a saddle surface Max will be -7 and Min will be 4
