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.

Add a clause in InterestingRangesForDisplay to detect strong variations.
This improve the graph for x^x or x^2+x+1 for instance.
Change-Id: I74214c2382cfe4b0e2603556dd8c6cbd450effc0
Added a method to Zoom to set a range to a specific ratio. This method
is used by InteractiveCurveViewRange::normalize.

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

Temperatures can be converted to and from degree Celsius and Fahrenheit.
When used in non-trivial calculations, they are always reduced to undef,
as the rules for manipulating relative scales are not well defined.

The solutions of equations that need numerical approximations to be
solved are now computed base on the undeveloped equation (instead of
fully the expended one used to identify polynomials)
This allow (x-10)^7=0 to yield x=10 as result (9.95 before)

Sequences can now be defined using specific terms form other sequences :
Un = n
Vn = u(3)
Initial values can also depend on other sequences.
Should there be a circular dependency, the sequences concerned will
display "undef" as value

Implemented std::nextafter to replace hand made one.
Methods next and previous are no longer making the difference between -0
and +0

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.

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.

The additional results on units now include conversions into both unit
systems (metric and imperial).
Change-Id: Ie0f12eb3735e775560b66c2cbd78bc9a659145bb
Added methods to return the standard format for each dimension,
depending on the chosen unit system.

A split (such as _h+_min+_s) can now be generated for distances, volumes
and masses using imperial units.
Change-Id: Ib3ad63614979eddd02fbe0e99f16cf09dcf7c1fc
BuildTimesplit (used to create expressions of the form h+min+s) is now
based on the more general BuildSplit.

When the country is USA, the units will be simplified to common imperial
units rather than metric.
Change-Id: Ia533527a429ac26526380e324b9543b359f3b400
The new units are :
distance mile, yard, foot, inch
mass pound, ounce
volume gallon, quart, pint, cup, fluid ounce
table spoon, tea spoon
