@brief A semaphore that can be locked by only one thread at a time.
Used to serialize access to some resource (such as a data member). Here's
an example:
@code
void
Log::setLevel(Level level)
{
Lock lock(_mutex);
_level = level;
}
@endcode
As indicated in the example, you will probably never use any member function
in this class. The 'Lock' class provides this functionality.
