Roman numbers, Cezar cipher

This app is tree little tools in one:
- number to Roman number converter: you can enter any number to be converted to old Roman number format
- string reverser: you enter any text into field and you get that text reversed back
- Cezar cipher: ROT13 simple 13letters shifted encode converter

For next releases I hope to add
- encripter/decripter
- login to save your messages
- more cool text tools
