I don't understand what is returned

Nobody has claimed this yet.

The [docs provide the following example](https://maartengr.github.io/PolyFuzz/tutorial/quickstart/quickstart/#getting-started):
```
from polyfuzz import PolyFuzz

from_list = ["apple", "apples", "appl", "recal", "house", "similarity"]
to_list = ["apple", "apples", "mouse"]

model = PolyFuzz("TF-IDF").match(from_list, to_list)
```
which returns
```
>>> model.get_matches()
From To Similarity
0 apple apple 1.000000
1 apples apples 1.000000
2 appl apple 0.783751
3 recal None 0.000000
4 house mouse 0.587927
5 similarity None 0.000000
```

I don't understand what is returned. If polyfuzz is doing pairwise comparion from `from` list to `to` list, it should return len(from)*len(to) rows. So 18 results in this case.

In the example, apple->apples, apple->mouse, apples->apple, apples->mouse and so on are missing.

Start with the linked Quickstart documentation and its `PolyFuzz("TF-IDF").match(from_list, to_list)` example, then inspect the `model.get_matches()` entry point. Clarify why the output has one row per item in `from_list` rather than every pair, and document what the `From`, `To`, and `Similarity` columns represent so the example's result is understandable.
