-- reflect user defined optTol in Lasso -- based on code from task 15 -- make sure each lasso problem being terminated correctly

-- works fine for help_spgl1 example. which can be seen from the publish file in task 16(help_spgl1)

-- next try on simu shots and l1 migration problem.

-- for convolution problem, generally decrease the residual faster. Both of those two situations, either method can give right amplitudes

-- for PQN if given more iterations, updatetau every iteration, the result is not so bad, but this increase the function evaluation time significantly.
Needs to be fixed. See script2.pdf
