Checking wether the range that has been computed is suitable is now
done in Poincare::Zoom by SanitizeRange.

Create a method to clean up an ill-formed range, ie a range whose bounds
are not finite, or where max <= min.

Rework the logic so that :
- an undefined function will be displayed with a clealry defined
null range.
- display both an undefined function and a correct function at the
same time will not affect the correct range.

Add a clause in InterestingRangesForDisplay to detect strong variations.
This improve the graph for x^x or x^2+x+1 for instance.

When displaying f(x) = undef, the range now defaults to an orthonormal
range, centered on the origin, with axis unit 1.

Change some parameters to improve the output of
RangeWithRatioForDisplay. Notably, change how the size of the range is
weighed.

When looking for a range with a certain ratio using
RangeWithRatioForDisplay, instead of looking for ranges of the form
0.01*1.1^n, search for ranges of the form a*10^k, with a being either 1,
2, or 5.

Added a method to Zoom to set a range to a specific ratio. This method
is used by InteractiveCurveViewRange::normalize.
Change-Id: Id3029439294ece02ea19fb6c6de90b9edc85d771
As margins are added later in InteractiveCurveViewRange::setDefault,
rounding abscissa at this point is premature.

The ability to perform a range search without changing the X range was
only there to accomodate the Yauto feature.

In Calculation, keeping the BACK key pressed can lead to iffy
simplifications and uninitialized expressions beign passed to
ShouldDisplayAdditionalOutputs and SetAdditionalExpressions methods.

Additional results are proposed for all units combinations that include
a non-base unit, in addition to units with special results.

When tuning the representative without tuning the prefix, the prefix
would not be reset to its default value, causing a problem for masses,
whose base prefix depend on the representative (k for grams, none for
the rest).
Fixes a crash when typing sqrt(_N) with country set to US.

In metric, sqrt(N) would be simplified to _N_kg^-0.5_m^-0.5_s instead of
_kg^0.5_m^0.5_s^-1.
We solve this issue by preventing simplification using derived units
in presence of rational exponents.

In Trigonometry::shallowReduceInverseFunction, the reduction of
atan(1/x) used the hard value of pi instead of its equivalent in the
selected angle unit.
This fixes a bug causing atan(1/tan(40°)) to be equal to π/2-40 instead
of 50.
