(defn map
`Map a function over every value in a data structure and
return an array of the results.`
```
Map a function `f` over every value in a data structure `ind`
and return an array of results, but only if no `inds` are
provided. Multiple data structures can be handled if each
`inds` is a data structure and `f` is a function of arity
one more than the number of `inds`. The resulting array has
a length that is the shortest of `ind` and each of `inds`.
```
[f ind & inds]
(def res @[])
(map-template :map res f ind inds)
