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).

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
ExpressionModel::expressionReduced does already call isCircularlyDefined
and returns undef if true.
The isCircularlyDefined method is then made private.
