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.

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.

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.
