 High Performance Combinatorics in C++ using vector instructions v1.0.1
 
 HPCombi is a C++17 header-only library using the SSE and AVX instruction sets,

 HPCombi was initially designed using the SSE and AVX instruction sets, and did
 not work on machines without these instructions (such as ARM). From v1.0.1

 Further ideas are:
 - Vectorization (MMX, SSE, AVX instructions sets) and careful memory alignment,
-- Careful memory management: avoiding all dynamic allocation during the computation,
-- Avoid all unnecessary copies (often needed to rewrite the containers),
-- Due to combinatorial explosion, sets often don’t fit in the computer’s memory or disks and are enumerated on the fly.
