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

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).

Added methods to return the standard format for each dimension,

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

BuildTimesplit (used to create expressions of the form h+min+s) is now

When the country is USA, the units will be simplified to common imperial
units rather than metric.

The new units are :
distance mile, yard, foot, inch

table spoon, tea spoon

Float<float> and Float<double> used to share the same expression type
(Float), and the distinction was made by comparing their size. However,
due to padding, their size could be the same, leading to some issues :
- On the simulator, in Calculation, type 1_mm^3 and go to the
additional outputs. One of the results would be -0.0003081979_µm^3.

To prevent incorrect approximations, such as cos(1.5707963267949) = 0, we lowered the precision value. This way,
the approximation is more selective. However, when ploting functions such as e^(i.pi+x), the float approximation fails
and therefore, the function appears "undef".
As a result we created two functions Epsilon that behave differently according to the number's type. When it is a double,
we want a maximal precision -> epsilon_double = 1x10^(-15), and when it is a float, we accept more agressive approximations
-> epsilon_float = 10 x 1x10^(-7).

Removed limitation in calculation of normal_distribution. It was used to
speed-up computation but yielded 0 for small values.
Previously P(X<5) with X->N(7,0.3162) gave 0 as a result
now it gives 1.26e-10
