[Forth](https://en.wikipedia.org/wiki/Forth_%28programming_language%29) is a stack-based programming language. Implement a very basic evaluator for a small subset of Forth. Your evaluator has to support the following words: - `+`, `-`, `*`, `/` (integer arithmetic) - `DUP`, `DROP`, `SWAP`, `OVER` (stack manipulation) Your evaluator also has to support defining new words using the customary syntax: `: word-name definition ;`. To keep things simple the only data type you need to support is signed integers of at least 16 bits size. You should use the following rules for the syntax: a number is a sequence of one or more (unicode) digits, a word is a sequence of one or more letters, digits, symbols or punctuation that is not a number. (Forth probably uses slightly different rules, but this is close enough.) Words are case-insensitive.
