Because we cannot use clock() and clock_t, because it does not exist in the library timer.h, we have to use an internal timer.
The timer should be precise enough to measure differences reliably up to 20kHz
(Example stepping: Half-Period-Time / 5)

The timer will count up to 2^16 = 65536-1 and then overflows to 0
Still todo:
Check effects of overflowing nextTick and overflowing timer
Example timer code:<br><br>
<code>// Using timer1 (16-bit)</code><br>
<code>TCCR1B |= (1 << CS10); // This sets the prescaler</code><br>
<code>TCNT1 = 0; // initialize counter</code>
<br>
<br>
Outside can then <code>TCNT1</code> be used as variable.<br>
