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).

of a line for axes: Origin + (Coordinate_vector - Origin) * parameter.
5. If plane goes trough Origin:
a) Find new random origin: find unit cube vertex, not crossed by a plane.
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
coordinate means that segment does not change sign, 1 value -> does
change. So new sign is (1 - 2 * new_origin): 0 -> 1, 1 -> -1
6. Run function that calculates miller indices from segments.
Args:
List of points. Each point is list of float coordinates. Order of
coordinates in point's list: x, y, z. Points are different!
Returns:
String that represents Miller indices, e.g: (-6,3,-6) or (2,2,2)

<p>Isn't the toy course great?</p>
<p>Let's add some markup that uses non-ascii characters.
For example, we should be able to write words like encyclop&aelig;dia, or foreign words like fran&ccedil;ais.
Looking beyond latin-1, we should handle math symbols: &pi;r&sup2 &le; &#8734.
And it shouldn't matter if we use entities or numeric codes &mdash; &Omega; &ne; &pi; &equiv; &#937; &#8800; &#960;.

UI part and inputtypes
----------------------
Miller module is used in the system in crystallography problems.
Crystallography is a class in :mod:`capa` inputtypes module.
It uses *crystallography.html* for rendering and **crystallography.js**
for UI part.
Documentation from **crystallography.js**::
For a crystallographic problem of the type
Given a plane definition via miller indexes, specify it by plotting points on the edges
of a 3D cube. Additionally, select the correct Bravais cubic lattice type depending on the
physical crystal mentioned in the problem.
we create a graph which contains a cube, and a 3D Cartesian coordinate system. The interface
will allow to plot 3 points anywhere along the edges of the cube, and select which type of
Bravais lattice should be displayed along with the basic cube outline.
When 3 points are successfully plotted, an intersection of the resulting plane (defined by
the 3 plotted points), and the cube, will be automatically displayed for clarity.
After lotting the three points, it is possible to continue plotting additional points. By
doing so, the point that was plotted first (from the three that already exist), will be
removed, and the new point will be added. The intersection of the resulting new plane and
the cube will be redrawn.
The UI has been designed in such a way, that the user is able to determine which point will
be removed next (if adding a new point). This is achieved via filling the to-be-removed point
with a different color.
