Merging is hard :'(

cargo fmt

Issue #4: Add `adds_required_by_dim` as output.

Add the boundary for the test data set Twoc

Add license

Update README a little more

Fix Markdown errors in the README

Move code to top level

Fix warnings and remove some dead code

Begin on rewriting stats and stats output.

Remove dead and commented out code

Remove double reduction variant runs.

format, and have a script patch things back together.

Add test tet file, and flush out some easy bugs

Fix warnings with old code

Greatly simplify the `reduce` method.

Begin on improved reduction implementation

Did a lot of things.

This is not tested at all, since CGAL is stupid.

Rework alpha_2d a little, and fix warnings

Move alpha values to `Persistence`

This makes more sense, but it's not optimal still.
