Allow math in value input fields

I'm interested in implementing this as this seems like a very good first starting point. Should I use a library like Keval or should Implement a small tokenizer and evaluator myself?

That would be great! I had thought about perhaps supporting currencies in the future. So that a currency is specified per group and new expenses are converted into this currency when entered. I think it would be quite elegant if users could enter the currency (or even multiple currencies) directly as a string when entering the expense. For example, “$23 + 22.46€”, which could then be converted into euros, if that's the group currency.

Of course, a custom solution would be a great basis for this, but I would also be happy if you just implemented it with Keval for now.

In any case, calculations would also fit perfectly into the input fields for the absolute splitting that you implemented in #33 (which I hope to have time to take a closer look at tomorrow).

Sounds like keval would be a good option, € and so on could be newly defined unary operators (maybe both as prefix and postfix)
