This is a module that encapsulates all open ended grading (self assessment, peer assessment, etc).
It transitions between problems, and support arbitrary ordering.
Each combined open ended module contains one or multiple "child" modules.
Child modules track their own state, and can transition between states. They also implement get_html and
handle_ajax.
The combined open ended module transitions between child modules as appropriate, tracks its own state, and passess
ajax requests from the browser to the child module or handles them itself (in the cases of reset and next problem)
ajax actions implemented by all children are:
'save_answer' -- Saves the student answer
'save_assessment' -- Saves the student assessment (or external grader assessment)
'save_post_assessment' -- saves a post assessment (hint, feedback on feedback, etc)
ajax actions implemented by combined open ended module are:
'reset' -- resets the whole combined open ended module and returns to the first child module
'next_problem' -- moves to the next child module
'get_results' -- gets results from a given child module
Types of children. Task is synonymous with child module, so each combined open ended module
