* t1ha = { Fast Positive Hash, aka "Позитивный Хэш" }
* by [Positive Technologies](https://www.ptsecurity.ru)
*
* Briefly, it is a 64-bit Hash Function:
* 1. Created for 64-bit little-endian platforms, in predominantly for x86_64,
* but portable and without penalties it can run on any 64-bit CPU.
* 2. In most cases up to 15% faster than City64, xxHash, mum-hash, metro-hash
* and all others portable hash-functions (which do not use specific
* hardware tricks).
* 3. Not suitable for cryptography.
*
* The Future will (be) Positive. Всё будет хорошо.
*
* ACKNOWLEDGEMENT:
* The t1ha was originally developed by Leonid Yuriev (Леонид Юрьев)
* for The 1Hippeus project - zerocopy messaging in the spirit of Sparta!
