commit 40d2f5d1ddacf71991adb447b163a19136ee2179
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Wed Nov 5 11:31:35 2008 +0100

    Fixed some minor spelling errors.

commit 931ece4838fcef7b9ec71761d224e2e1cd11a89d
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Wed Nov 5 11:22:19 2008 +0100

    Changed code from using cl_UP_MI to using umodpoly. The cl_UP_MI interface was
    inconvenient to use and caused several very difficult bugs (some were still
    unresolved before changing to umodpoly!).
    
    Fixed severe bug in multivariate factorization. The condition that all modular
    factors should be relatively prime in the base ring was violated. This caused
    the factorization sometimes to go into an infinite loop.

commit e989719ca767691eb75b34785baaaed716ea2624
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Mon Nov 3 15:50:31 2008 +0100

    Added code for distinct degree factorization.
