opt.reg is not used in phaselift

[Zongyu Li]

In

phasepack-matlab/solvers/solvePhaseLift.m

Line 82 in aac4525

 muFinal = opts.regularizationPara;   % Regularization Parameter 

where we say

muFinal = opts.regularizationPara;   % Regularization Parameter

but later in the code we define

mu = norm(eig(AtL(b0)),1)*opts.tol;

And then we use mu everywhere,
so I don't see how muFinal is useful in this code.
