Summary: Range library for C++14/17/20, basis for C++20's std::ranges

Description:
Ranges are an extension of the Standard Template Library that makes its
iterators and algorithms more powerful by making them composable. Unlike other
range-like solutions which seek to do away with iterators, in range-v3 ranges
are an abstraction layer on top of iterators.
