add: rudimentary Bertone/Cheze/Galligo absolute factorization
chg: deleted debug output from absfact
chg: documentation
chg: renamed fac_absfact.* to facAbsFact.*
chg: more changes due to renaming
chg: changes to output and documentation
chg: added absolute irreducibility test
chg: added new templates to hold absolute factors
chg: changes due to new template
chg: changes to build system due to new templates
chg: added mmore functions to templates
chg: added naive implementations of abs. irred. tests from
     Bertone, Cheze, Galligo
chg: top level abs factorization interface
chg: debug output and experimental code
chg: Singular interface to factory's absBiFactorize
chg: convenient way to call absBiFact (i.e. handling of ring changes) via
     absBiFactorize
TODO: may be handle Gerhard's special output for absPrimDec
fix: univariate abs. factorization
chg: code clean up and optimizations
chg: docu + example
