----------------------------------
Summary: Add ZIP_WITH and ZIP_WITH_INDEX Functions in Stellar
Key: METRON-1057
URL: https://issues.apache.org/jira/browse/METRON-1057
Project: Metron
Issue Type: New Feature
Reporter: Josh Meyer
In addition to the new `ZIP` functions in Stellar, we should add a `ZIP_WITH`
and `ZIP_WITH_INDEX` functions. These have been implemented in other languages
(Haskell). Below are examples of these functions.
```
ZIP_WITH([1, 2, 3], [1, 2, 3], (a, b) -> a + b) == [2, 4, 6]
ZIP_WITH_INDEX([1, 2, 3]) == [[0,1], [1,2], [2,3]]
```
