"""
Converts lengths of which the plane cuts the axes to fraction.
Tries convert distance to closest nicest fraction with denominator less or
equal than 10. It is
purely for simplicity and clearance of learning purposes. Jenny: 'In typical
courses students usually do not encounter indices any higher than 6'.
If distance is not a number (numpy nan), it means that plane is parallel to
axis or contains it. Inverted fraction to nan (nan is 1/0) = 0 / 1 is
returned
Generally (special cases):
a) if distance is smaller than some constant, i.g. 0.01011,
than fraction's denominator usually much greater than 10.
b) Also, if student will set point on 0.66 -> 1/3, so it is 333 plane,
But if he will slightly move the mouse and click on 0.65 -> it will be
(16,15,16) plane. That's why we are doing adjustments for points coordinates,
to the closest tick, tick + tick / 2 value. And now UI sends to server only
values multiple to 0.05 (half of tick). Same rounding is implemented for
unittests.
But if one will want to calculate miller indices with exact coordinates and
with nice fractions (which produce small Miller indices), he may want shift
to new origin if segments are like S = (0.015, > 0.05, >0.05) - close to zero
in one coordinate. He may update S to (0, >0.05, >0.05) and shift origin.
In this way he can recieve nice small fractions. Also there is can be
degenerated case when S = (0.015, 0.012, >0.05) - if update S to (0, 0, >0.05) -
it is a line. This case should be considered separately. Small nice Miller
numbers and possibility to create very small segments can not be implemented
at same time).

b) Repeat 2-4.
c) Fix signs of segments after Origin shift. This means to consider
original directions of axes. I.g.: Origin was 0,0,0 and became
new_origin. If new_origin has same Y coordinate as Origin, then segment
does not change its sign. But if new_origin has another Y coordinate than
origin (was 0, became 1), than segment has to change its sign (it now
lies on negative side of Y axis). New Origin 0 value of X or Y or Z

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

Returns the locations of each of child modules.
Overriding this changes the behavior of get_children and
anything that uses get_children, such as get_display_items.
This method will not instantiate the modules of the children
unless absolutely necessary, so it is cheaper to call than get_children
These children will be the same children returned by the
descriptor unless descriptor.has_dynamic_children() is true.
