Push ID
pushid generates a unique Push ID for each invocation of the command. The code is copied from
this gist. The only modification is
to main() so that it outputs a single Push ID.

Overview ¶
* * This code comes from https://gist.github.com/themartorana/8c8b704432c8be1fed9a * Only modification is change in main function to output just one pushid. * * 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).
