Because they are not walls, they are boxes with finite 
length/depth/thikness and mass. They can be dynamic, unlike the "walls" 
we use usually, which are infinite planes (they can also have contacts 
on each of 6 faces).
We should implement infinite walls in fact, as they would take less time 
for contact detection.

In ElasticContactLaw.cpp, why the code with 'approximated rotations' 
is used, or in other words, is there a particulier reason to comment the 
code with 'exact rotations' ?

"Approximated rotation" is much faster (this is Janek's work). Having 
the exact version commented (rather than nothing) is good, so you can 
always switch to exact rotations by commenting/uncommenting each method 
and benchmarking.

Going back to marking students, so borring!...
