Adaptive Learning Environment (ALE)

A simple example for our Groovy adaptation engine.

The most important files are:

grails-app/ale/LoggingFilters.groovy
  - Example filter, performs simple logging
grails-app/conf/BootStrap.groovy
  - Some initial data for tests is generated here
grails-app/controllers/ale/AleController.groovy
  - The one and only controller; delegates all of its work to
grails-app/services/ale/AleService.groovy
  - The implementation of the user-visible services
grails-app/domain/*
  - The domain model

A user interface will be added shortly.

Example interaction (manually formatted for better readability):
