[Axiom-developer] new algebra documentation

[daly]

Alasdair, Jose,

I've added new help documentation for some of the algebra domains. 
Specifically there are new help files for:

AssociationList   BalancedBinaryTree   BasicOperator
BinaryExpansion   BinarySearchTree     CardinalNumber
CartesianTensor   Character            CharacterClass
CliffordAlgebra   Complex              ContinuedFraction
CycleIndicators   DeRhamComplex        DecimalExpansion

More are in the pipeline as soon as they pass testing.

You can get the latest at <daly.axiom-developer.org/spadhelp.tgz>
  1) cd to $AXIOM/doc
  2) Download the file, 
  3) tar -zxf spadhelp.tgz
  4) start Axiom
  5) type
      )help CliffordAlgebra
