Now with beginnings of some language support for French, Spanish, Dutch, German, Norwegian, Russian (I need help from translators see line 72 or so of abacus.js). It is all driven by a single JavaScript program with input parameters in the html.

There is a feature for teachers to test students on the use the abacus. This would give the ability to create your own tests. Results would go into a results directory.
