This is an implementation of TimSort, the default sorting algorithm used in Python and newer versions of Java.
This is still an extreme work-in-progress, and performance has vast room for improvement.
The benchmarks are the only part that doesn't work in pure stable rust.
benches/bench.rs
is for rust-TimSort, benches/bench_default.rs
is for the
default MergeSort that comes with Rust.
