Version 0.3.2: 2009/2/13
  Fixed various packaging and test inconsistencies

Version 0.3.1: 2008/12/16
  Bug fix release: the composition of ring homomorphisms was very occasionally
  incorrect, causing errors to be generated when computing the Lyndon-Hoschild-
  Serre spectral sequence of a few groups of order 64.

Version 0.3: 2008/12/10
  Major internal changes and bug fixes to the Lyndon-Hochschild-Serre spectral
    sequence code
  New HAPRingHomomorphism datatypes 
  New KernelOfModuleHomomorphismGF function and ResolutionPrimePowerGroupGF2
    function which offer an alternative to the earlier low-memory version
    (it is currently not _better_ than the earlier version, but with more
    work it could be)

Version 0.2.1: 2008/9/15
  Now requires HAP version >= 1.8.9
  Improvements to ModPCohomologyRingPresentation. It now returns the known
    result if the group is cyclic, and splits the problem if the group can be
    decomposed into direct factors. It now recursively calls itself to calculate
    the presentations for smaller groups, so the presentations will be correct
    by induction.

Version 0.2: 2008/8/22
  Added functions to compute and use the Lyndon-Hochschild-Serre spectral
    sequence to compute provablycorrect mod-p cohomology rings and 
    Poincare series.
  Manual now split into two: a userguide and a datatypes reference manual
  New test files, including testing all of the manual examples

Version 0.1.3: 2008/2/8
  Improvements and bug-fixes to derivations, and added HomologyOfDerivation 
  function

Version 0.1.2: 2007/1/28
  Added derivations, in particular the KernelOfDerivation function
  Fixed warnings about multiple defined operations (not visible because of HAP 
  bug)

Version 0.1.1: 2007/12/20
  Added PresentationOfGradedStructureConstantAlgebra() function

Version 0.1.0: 2007/09/25
  First public release
