Agree. The storage can be reused later. In that case, we could simply
use vector's clear method instead of assigning an empty vector.

I would, but never used doxygen before.

It is not a bug, but more like pedantic adherence to the coding style.
performCalculations is declared virtual in LazyObject. We could drop
the keyword virtual when overwriting performCalculations in
Instrument, just like we drop the keyword virtual when overwriting all
other virtual methods in derived classes.
