commit 2b0ad5c381dc081cc4066b0c5f939f5169ad9ab3
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Thu Nov 13 11:13:05 2008 +0100

    Fixed lots of bugs in factor_multivariate().
    
    factor_univariate() takes now the content of the polynomial into accout when
    choosing a prime. It also returns the chosen prime. This supports the
    factor_multivariate() code.
    
    Polynomials are expanded before calling factor_sqrfree(). This avoids problems
    with some input polynomials.
    
    Added static qualifiers to all hidden functions.

commit a17a77e5c3d4ec2a92804debac65c75921f0156d
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Tue Nov 11 10:33:29 2008 +0100

    Fixed a bug in squarefree(). Some polynomials were erroneously classified as
    square free (e.g. x^prime+1).
    
    Fixed a bug in multivar_diophant() causing  sporadically an infinite loop.
    
    Improved lifting bound code.
    
    Univariate lifting can now use a cache for the modular factors. At the moment,
    this gives no measurable speed gain.

commit edc92b7a463993da62357fb4afad053e8c6d0771
Author: Jens Vollinga <jensv at balin.nikhef.nl>
Date:   Mon Nov 10 13:38:11 2008 +0100

    Added modular square free factorization.
    Completed distinct degree factorization.
    Univariate polynomial factorization uses now upoly.
    Merged class Partition and function split into class factor_partition.
