Add "Dive" input function

Need a "dive" input function which simply dives to another property.

Given the following result set

{
  "results": [
    { "p1":"v1" },
    { "p2":"v2" },
    { "p3":"v3" },
  ]
}

Diving to ".results" leads to an input of

[
    { "p1":"v1" },
    { "p2":"v2" },
    { "p3":"v3" },
]

In a spread, all results (if the dive leads to an array) are put in-order the spot of their parent.
