Léa Saviot 53705fb333 [apps/graph_ctrlr] Reload range if no previous model is present
We memoize the checksum of the x first models, and we check that one of
these models is still present when the graph view appears. If so, we do
not reload the range, other wise we reload it.

Scenario:
f(t) = [t^2  t+1] in parametric
Display the graph
f(x) = 1 on ]-inf;0]
g(x) = 2 on [0;inf[
Display the graph -> the range did not change
