7f6a3f0fc1 [apps/curve_view] Fix KDCoordinate overflow 
Scenario: (with the current auto zoom algorithm)
Graph f(x) = x! -> Auto axes are x=[-13,17647;13,17647],
y=[3628793;2628807]
Press "0" "EXE" to go to x = 0 -> Axes are x=[-13,17647;13,17647],
y=[-0.8612717;13.13873]
Press auto
Press "0" "EXE" to go to x = 0 -> the assertion about KDCoordinates
breaks.

1bee23cf4f [apps/graph] Reworked function caching 
Instead of being memoized all at once before display, functions values
are now stored at evaluation time. Fixed some quirks with caching
preparation.

42fcf557b8 [apps/graph] Limited number of cached functions 
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.

95fef86ec0 [apps/graph] Activated caching for graph drawing 
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.

8e025b0823 [apps/shared] CurveView: avoid overflowing KDCoordinate 
This fixes the following bug: add the sequence, u(n)=2^n. On the graph,
go to "sum of terms" and try to sum terms from 0 to 18 by moving the
cursor. It hangs.

84768472bd Explicit std::min/max template usage 
This is unfortunately required in several cases:
 - Sometimes when we use either float and double (this should be changed)
 - Because KDCoordinate is not an int, so any arithmemtic promotes it to
an int
 - Because we mix pointer differences and ints

private method used by 'drawLabelsAndGraduations' and 'drawLabel' to
determine the position of the label knowing the position of the
graudation and its relative position
