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.

It's probably better to run just one of the variants, and output the data
to some other format. For the stats things we could use some other standard
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.

Fix Makefile, add comments, and break persistence.rs

Have started factoring out the `r_when_born` from `Simplex`, since
this shouldn't be there. The only thing the `persistence` module
should need to know of the simplices are their boundaries.

Should consider moving the alpha thing out, or to another module.

Add more cli arguments

Should also do some cleanup with the `Simplex` code.

Move persistence things to new file

We'd like to keep `main.rs` to be argument parsing and stuff like that.

Add a bunch of comments

Move output things to `output.rs`, and fix warnings

Increase the cutoff, so that the flower is filled

Improve tex table output

More dimension specific numbers

Output column adds for different dims in the tex table
