[apps/graph] Activated caching for graph drawing

Browse Source 
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.
