Yes, flash and stack are in bytes. `Time' is a number of
CPU clocks. It is calculated by simulating (simulavr).

This numbers include all modules which are concatinated
for tested function. As a rule they are an asm writen
modules, so it is no matter for comparison puprose.

Size and time do not include a ones needed to prepare
the function args.

It is amusing, that here there is no opposition of the
size and speed: practically everywhere reduction of
the size is accompanied by acceleration of performance.
