+ * CombGenerator generates COMBs (combined UUID/timestamp)
+ *
+ * The CombGenerator, when used with the StringCodec (and, by proxy, the
+ * TimestampLastCombCodec) or the TimestampFirstCombCodec, combines the current
+ * timestamp with a UUID (hence the name "COMB"). The timestamp either appears
+ * as the first or last 48 bits of the COMB, depending on the codec used.
+ *
+ * By default, COMBs will have the timestamp set as the last 48 bits of the
+ * identifier.
+ *
+ * ``` php
+ * $factory = new UuidFactory();
+ *
+ * $factory->setRandomGenerator(new CombGenerator(
+ *     $factory->getRandomGenerator(),
+ *     $factory->getNumberConverter()
+ * ));
+ *
+ * $comb = $factory->uuid4();
+ * ```
+ *
+ * To generate a COMB with the timestamp as the first 48 bits, set the
+ * TimestampFirstCombCodec as the codec.
+ *
+ * ``` php
+ * $factory->setCodec(new TimestampFirstCombCodec($factory->getUuidBuilder()));
+ * ```
