Abstract parent class for Generators.
Concrete generators implement generateBodies() to produce a list of task element bodies,
which are wrapped in task elements based on the template.
The text of the input element is passed to generateBodies.
A Compound container is created for the list of tasks,
with all the attributes except name and type of the original Generator task.
The TaskFactory creates a Task object from this, which is then processed.
...some way to generate the Task bodies...
TODO complete and re-implement SQLGeneratorTask

Each object is responsible for adding itself to the context and reporting errors through the context.
Acts as a wrapper for doValidate() in order to do housekeeping.
Handles adding task to the heirachy and the failed error message.
Handles locally-set class paths.
