In stats when selecting an action on a column, all actions listed after
the one selected were applied. Adding breaks to the switch solved the
issue

Some code to prevent the input field from scrolling when switching to
the history in layout mode causes problems :
- With a calculation in the history, type an empty matrix or fraction.
Then with the cursor on an empty square, go to the history. The
square will appear shifted to the right.

Calculation's input is now only saved and restored when the app truly
closes or opens, instead of whenever the EditExpressionController enters
or leaves the responder chain (which also happens when the user switches
to the history or the toolbox, or triggers a syntax error).

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.

This fixes issues #1541. Formulas as asin(sin(X)) with X a large number
were failling to simplify themselves into the image interval of asin
ex : previous version asin(sin(6)) = 6
new version asin(sin(6)) = -2pi+6

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

Changed dumpLayout's name to moveCursorAndDumpContent, as the name
suggested the method was only usable on layouts (while it also works on
text). The method is also no longer marked const, and the previous name
could imply that it had no side effects.
Likewise, renamed restoreLayout to restoreContent.

When closing and reopening Calculation, if the cursor was on an
EmptyLayout, this layout would be invisible, instead of being denoted by
its usual yellow square.
This also fixes a bug that would leave the grey squares in matrices when
leaving and reopening the app, causing a failed assertion on the simulator.

Closing the Calculation app because of a full pool would crash the
device, by attempting to dump a layout with no node.

FLT_EPSILON is now compliant with the definition : the difference

This fixes a bug where, when drawing 1/x, a vertical bar would appear on
0, because of false positive cache hits.

Instead of being memoized all at once before display, functions values
are now stored at evaluation time. Fixed some quirks with caching
preparation.

The caches used for function values memoization are now stored in
ContinuousFunctionStore : there are now only a fixed number, instead of
one per function. This effectively enables caching only for the first
few functions on screen, while reducing the memory usage.

Added a default argument to CurveView::drawCurve : a function to initiate the
memoization of continuous functions. The function is implemented in
ContinuousFunctionCache and provided by GraphView. This should be invisible
to other types of curves that rely on CurveView::drawCurve.

When evaluating a ContinuousFunction for a float value, the function
will first try to ask its cache (if it has been filled beforehand).

ContinuousFunction now has an attribute of type ContinuousFunctionCache,
implementing methods to store and retrieve 320 float values, in order to
speed up function display in Graph.

Method InteractiveCurveViewRange::panToMakePointVisible now moves the
range of a whole number of pixels when panning horizontally. This allows
the cache of cartesian functions not to be invalidated.

It appeared that without the packed keyword, the compiler did not handle
access to unaligned record data members, which leads to crashes on the
device.
