Hi, I'm using the Revalin ruby and works awesome. I lost my litecoin wallet password but I think there might me a combination of two or three words.

The problem is that I usually swap one or two vowels by numbers and I can't remember which of them I did.

I'd appreciate a lot if you help me with the function that, giving a word by parameter, it returns a list of all the words with different combinations, where a might be replaced by 4, e by 3, i by 1 and o by 0. I only need that function, the Revalin code is pretty clear.

I know that is something that I could do manually. I have 2^n combinations, where n is the number of vowels on a word.
