Improve performance and add profiling tooling Add tags, todo, *.bench, *.svg and bench_output to .gitignore Add test/bench.sh script. bench.sh runs the `bench` command on each test/long*txt file with range 3:5 and saves the output to a file for comparing performance across file sizes. Inline printing in get_choice_slice Change BufWriter<..stdout..> to BufWriter<T> Add MockStdout for testing printing Add more reverse range tests Simplify word finding with a more uniform bounds check. Add Makefile for generating flamegraphs Redefine Choice struct as a start and end integer Improve algorithm for finding words to print Settle exclusivity at Config construction time Add tests for nonexistant field_seps Add regression test for preceding separator Use handle.write instead of write! macro for tremendous speed up
