[Moose-dev] what is the pattern to add a custom importer performing action after default import?

Doru long time ago :) there were importer post action plugin that we could register to Moose. I reread my comment on Tasks and friends (I hate hate all the classes with not a single comment - so I will take some time when I can to see what I can write but this is really terrible) - this were the comments I wrote when I wanted to build the new importer. Now they do not describe the API and how to plug a new Task. So how do we declare to an importer that a task should be run automatically after a model is created? May be by creating a compositeTask but I want it to run after the main model is created. Stef
