 ===== Example =====
+Send ''a'' in Serial Monitor to store the next number, ''p'' to retrieve the most recently stored number, or ''c'' to clear the buffer. Send one character at a time to observe the behavior.

+uint16_t nextNumber = 0;
-FILO(0, digitalRead(0), digitalRead(1), D[0], filoOut, 10);

+  const bool ok = FILO(0, store, retrieve, nextNumber, lastNumber, 16, clearBuffer);  // Store a number; on a pop signal, retrieve the last stored number.
+  FILO(0, false, false, nextNumber, lastNumber, 16, false);  // Return both inputs to LOW so the next character creates a new rising edge.

 ''IN'', ''OUT'', ''CU'' and ''CD'' act on rising edges. Use a unique ''id'' for each counter or buffer, and keep ''size'' to the required minimum.
