/** | |
* Fancy ID generator that creates 20-character string identifiers with the following properties: | |
* | |
* 1. They're based on timestamp so that they sort *after* any existing ids. | |
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs. | |
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly). | |
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the | |
* latter ones will sort after the former ones. We do this by using the previous random bits | |
* but "incrementing" them by 1 (only in the case of a timestamp collision). | |
