/** If we don't want to force vtables, we can make the destructor inline and protected.

* the compiler can see that this is safe (thus no unnecessary warnings). Preferrably
* though this class has a protected inline destructor.
*
* When I use Xcode on the MacOSX, I would prefer to not see the warnings that the
* destructor of this class is not virtual, and speed is not the primary concern in
* that build (as that build is used mostly for debugging).
*
* HIDE_UNIMPORTANT_COMPILER_WARNINGS can be defined in case one wants to get rid of
* compiler warnings, as opposed to having maximum running speed.
