 Element extrapolation transformation
 ------------------------------------
 
-A specific transformation (see previous section) is defined in order to allows 
the evaluation of certain quantities by extrapolation with respect to another 
element (in general a neighbour element). This is not strictly speaking a 
transformation since the point remain unchanged, but the evaluation is just 
made in another element extrapolating the shape functions outside this element. 
This transformation is used for stabilization term in fictitious domain 
applications (with cut elements) where it is more robust to extrapolate some 
quantities on a neighbour element having a sufficiently large intersection with 
the real domain than evaluating them on the current element if it has a small 
intersection with the real domain. The functions allowing to add such a 
transformation to a workspace or a model are::

extrapolation has to be made. On the element not listed in the map, no
