We need to support parsing

1, 2 and 3

as

1 , 2 and 3

But when we do format we do format it back to:

1, 2 and 3

So 1, and 1. are not stacked as single reference by default, unless we use something like "1," or "1."

That should simplify natural language processing.

We also should not parse math formulas like:

1+1,1/1,1*1

As a single reference, instead it also should be parsed as

1 + 1 , 1 / 1 , 1 * 1

So we should support not only punctuation, but also math symbols.

Formatting should be configurable in case of math simbols and punctution. So we should be able to see Links Notation as it was parsed, but also should have ability to format it nicely to make it human readable.
