I am asking this because in the measurements-samples structure, the search
for a sample is linear with linked lists and logarithmic with balanced
treees. If we plan to have a few samples per measurements, a linked list
will suffice, on the other end, if a measurement can have a lot of sample
(in the thousand range) the a balanced tree structure is more adequate.
