A lightweight benchmarking library which:
* uses linear regression to screen off sources of constant error;
* handles benchmarks which must mutate some state;
* has a very simple API!
```rust
use easybench::{bench,bench_env};
// Simple benchmarks are performed with `bench`.
println!("fib 200: {}", bench(|| fib(200) ));
println!("fib 500: {}", bench(|| fib(500) ));
// If a function needs to mutate some state, use `bench_env`.
println!("reverse: {}", bench_env(vec![1,2,3], |xs| xs.reverse()));
println!("sort: {}", bench_env(vec![1,2,3], |xs| xs.sort()));
```
Running the above yields the following:
```none
fib 200: 38 ns (R²=1.000, 26053498 iterations in 155 samples)
fib 500: 109 ns (R²=1.000, 9131585 iterations in 144 samples)
reverse: 3 ns (R²=0.998, 23684997 iterations in 154 samples)
sort: 3 ns (R²=0.999, 23684997 iterations in 154 samples)
```
