removed GAP4.4 legacy stuff from init.g and read.g
enhanced HomalgFieldOfIntegersInSingular to access all finite fields
used GaloisField( p ) instead of Integers( p )

which causes segfaults
simplified code in CommonHomalgTableForMAGMATools.Eliminate
added CommonHomalgTableForMAGMATools.PrimaryDecompostion
simplified code of homalgTable entry PrimaryDecomposition

in CommonHomalgTableForMAGMATools and CommonHomalgTableForSingularTools
added new entry RadicalDecomposition to CommonHomalgTableForMAGMATools
added new entry AffineDimensionOfIdeal to CommonHomalgTableForMAGMATools
fixed Sum in entry

in CommonHomalgTableForMAGMATools,
   CommonHomalgTableForMacaulay2Tools,
   CommonHomalgTableForGAPHomalgTools
secured gcd in CommonHomalgTableForMapleHomalgTools

Added CommonHomalgTableForSingularTools entry Evaluate

depends on HomalgToCAS v2013.06.01
HomalgRingOfIntegersInSingular cannot pass rational parameters!
RingForHomalgInSingular now supports "finalizer" functions

we need this to call minpoly prior to setting the distinguished ring elements in
. HomalgRingOfIntegersInSingular
. HomalgFieldOfRationalsInSingular

needs MatricesForHomalg v2013.06.06
Zero, One, and MinusOne now have true pointers
