Added a tolerance when checking orthonormality, so that ranges that are
nearly orthonormal will be made orthonormal.

Restore the permanence of the cursor between accesses to the graph
window.
The cursor used to be reset when the models had been modified. As there
is no longer a system in place to track these modifications, we manually
check if there is a curve beneath the cursor before reseting it.

The normalized status would not be refreshed after a call to setDefault
triggered by InteractiveCurveViewController::viewWillAppear.

The method FunctionGraphController::yRangeForCursorFirstMove expands the
Y range to include the values of the first cursor moves on the left and
the right of the center. It has been modified to preserve
orthonormality.

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.

The Auto mode for curve ranges must be deactivated when moving the
cursor outside the screen and when activating navigation (formerly
Zoom).

This method of InteractiveCurveViewRangeDelegate was only used to
compute the Y range when Yauto was on.

The graph range used to be reset to default whenever all functions were
modified. As we no longer want to reset the range without the user's
input, we do not need to track whether the functions changed at all.
/!\ As of this commit, there is no longer a way to restore the default
zoom, until a new automatic zoom button is added.

The banner used to display u(n+1)/u(n+2) if the sequences were not
explicit. This was incorrect and fixed

Forced the top cell of the country table to be cropped in the middle,
cutting the text, to avoid the cell looking squashed.

When choosing a language and then pressing back from the country menu to
get back to the language menu, the previously selected language remains
selected.

u(n+2) = u(n+1) + u(n) + u(2)
u(0) = 2
u(1) = 2
Crashed because the global context was not checking if the sequence was
badly referencing itself

Cache did not check that the step was the same before panning, causing
old values to remains cached.
e.g. :
- Type f(x) = x, and plot it.
- Go to Axes, and set Xmax = 0.
- Confirm

Fix a bug preventing the cursor from moving to other curves using UP and
DOWN when the y value was undef.
To reproduce :
- In Graph, define f(x) = 1 and g(x) = ln(x), then draw the curves
- Press DOWN to select g
- Press LEFT until g is not defined anymore
--> Pressing UP or DOWN won't allow you to select f
