/*!
WHAT THIS OBJECT REPRESENTS
This is an implementation of the timer_abstract.h interface. It is very
simple and uses only one thread which is always alive in a timer_heavy.
The reason this object exists is for historical reasons. Originally, the
dlib::timer was a multi-implementation component and the timer_heavy was
its first implementation. It was superseded later by the more efficient
dlib::timer. However, timer_heavy is still around so that
dlib::timer::kernel_1a has something to refer to. This way, old client
code which somehow depends on the same thread always calling a timer action
function isn't going to be disrupted.
