Salut! This week was a bitter-sweet one. It was immensely frustrating and gratifying at the same time. I spent a large part of the week looking for hard to find bugs and fixing them. I'll attempt to list these nasty creatures below:

- The first one relates to a mistake in the construction of the list r in same_charclass? in the slope = 0 case. A ',' (comma) was used for combining two elements in the list but cons should have been used instead.
- A couple of more changes related to computing unsafe factors in factor_newton and avoiding repeated computations in factor_minmult1 were rendered redundant based on the final modification (more on it in the last point).
- I also fixed the order of multiplication in the adjoint case in try_factorization. Earlier, the inverse of the leading coefficient of srl was used as the left operand in the multiplication, though it should have been the right one.
- Operators passed as arguments to same_charclass? are now made monic before further computation is performed on them. This avoids the errors arising from cases where the operators have different leading coefficients.
- I figured out that I was passing the wrong singularity and factor to factor_minmult1 and hence I changed the code so that factor_minmult1

is no longer used. I now believe that the factorizer should work as far as the methods from chapters 2 and 3 are concerned.
