Fifo modes in example seem incorrectly commented

[mspoorendonk]

The source code of the library says:
uint8_t fifoMode; //can be 0x0,0x1,0x2,0x3

The FifoExample.ino says:
//fifoMode can be:
// 0 (Bypass mode, FIFO off)
// 1 (FIFO mode)
// 3 (FIFO until full)
// 4 (FIFO when trigger)

That seems inconsistent.
