In UnitConvert::shallowBeautify, an orphan expression would be reduced
without reaffecting the reduction's result. The reduction not being
taken into account would cause problem when handling undef values.

The new zoom implemented for ContinuousFunction is now factorized inside
Function to benefit the Sequence class. The same things is done to code
added to Graph::GraphController, which is moved into
FunctionGraphController.
This removes the reimplementation of several methods, most notably
computeYRange, as the implementation for function is general enough to
work on sequences.

The auto zoom did not display the X axis when drawing positive curves
with roots, such as sqrt(x).

Additional checks have been added to ensure that the first move of the
cursor from the center of the graph would not cause the window to pan up
or down.

Method characteristicXHalfRange was used to compute the range on which
to display cartesian function in Graph. With the new zoom algorithm,
this method is deprecated.

Initial zoom for displaying curves is computed according to the
following rules :
- For polar and parametric curves, the algorithm has not changed.
Vertical and horizontal ranges are chosen in order to display the
full curve with orthonormal graduations.
- For cartesian curves, the horizontal range is chosen in order to
display all points of interest (roots, extrema, asymptotes...).
The vertical range is fitted to be able to display those points, but
also cuts out points outside of the function's order of magnitude.

In Graph, the weak ReductionTarget would cause _X^0 to not be simplified
to 1, and would break an assertion in
Unit::chooseBestRepresentativeAndPrefix.

When factoring 1^inf * 1^-inf with Multiplication::factorizeBase, an
Undef factor would appear an be carried into the reduced multiplication.
We escape early in this situation by returning Undef.

The addSibling method sometimes did not take into account the offset
introduced by adding parentheses, leading to some issues :
- Type 2 SQUARE RIGHTPARENTHESIS LEFT SQUARE. Parentheses are added
but the new square should be outside, between the two right
parentheses.

When typing Square in 2D Edition mode, the cursor would not be
repositionned correctly, leading to some issues :
- Typing 2 POW 3, pressing RIGHT to return to the baseline, then
typing POW again adds parentheses around 2^3, as is mathematically
correct. Typing 2 SQUARE, then POW, would show 2^2^_, while
the user really typed (2^2)^_.

poincareCircuitBreaker requires the Back key to be pressed for at least
50 ms before interrupting a computation.
This is effectively invisible for the user, but fixes a bug in
Calculation :
- When leaving the additional results for a result using units by
pressing the Back key, a reduction preceding a call to removeUnits
would be interrupted, causing an undefined behaviour.

After choosing a language at onboarding, the country menu now has a

Italian...)

With the imperial system selected, volumes are expressed as volume in
Calculation's results, instead of cubic lengths.
Change-Id: Ib6c0a1a595dce8ae8db6371b41af818b3fdc6236
In additional outputs, a volume is now splitted as :
_gal+_qt+_pt+_cup
instead of :
_gal+_cup+_floz

1. Information about a unit's dimension now uses inheritance.
_m is an instance of DistanceAlias, which is derived from Alias.
A UnitNode now keeps a pointer to an Alias and one to a Prefix.
All aliases are still defined as constexpr.
This cleans up a lot of the code used namely for computing the
additional outputs in Calculation.
2. Instead of being defined with a string, each unit is described by its
ratio with the base SI unit (ex: _L is 0.001 instead of "0.001_m^3").
This greatly speeds up the calculations using units, as the algorithm
to find the best unit used to parse the definition.

The symbol for pint (_pt) conflicts with the symbol for pico-tonne. To
solve that, prefixes for tonnes are now restricted to the positive
prefixes : k, M, G, T.

Instead of relying on the order in which the apps are passed at compile
time, the look of the Home app is defined in a config file, and depends
on the country chosen.

The additional results on units now include conversions into both unit
systems (metric and imperial).

A split (such as _h+_min+_s) can now be generated for distances, volumes
and masses using imperial units.

Classes LanguageController and CountryController have been fused into
one class LocalizationController, as they were very similar. This allows
the Settings and OnBoarding apps to only keep one controller for both

Instead of being hardcoded in the python script, preferences specific to
each country are defined in the country_preferences.h and .csv files.
Change-Id: I71e276341e1586935b4d5814be5b1be80fa170a0
Each country comes with an set of preferences, built at compile time by
apps/i18n.py, used to define :
- the exam mode
- the method for computing quartiles
- the unit system in which to output the results with units
Functions to access those preferences are available in
via sharedGlobalPreferences.

As some definitions now depend on the selected country, tests for the

and that each method yields the correct results.
