Some tests, some documentation, some examples of use

As pointed out in #2
It sure would be nice to have some tests for this.

Even ones that don't actually check the values, and just show how to use it without throwing errors.

Right now, I have no clear idea what any of the fields to the functions do.
In particular I don't know if the edges are 1 indexed or 0 indexed.

It would be really nice to have some simple examples.
Presumably you made this binding for a reason, so have some code you used it on?

BlossomV is a fairly important library in a number of fields, so it is great to have a julia binding for it.

Hi,

I made this binding because I needed a perfect matching algorithm for a numerical simulation I did a while ago. You can find an example for using this library in the function starting at
https://github.com/mlewe/thermalization-simulations/blob/master/toric.jl#L194
The code hasn't been updated in a while and unfortunately doesn't run under a current version of julia.

The edges are 0-indexed integers.

I can try to write some tests to showcase how the intended use looks like, when I get the time for that.
