Key-Value pair

In Deriscope terminology, a Key-Value pair is a pair consisting of a
Key and a Value
Its importance lies in the fact that the Deriscope spreadsheet function
ds expects as input a collection of Key-Value pairs and often returns Deriscope Objects, of which the internal structure is represented as a collection of Key-Value pairs
But even non-Excel interfaces to Deriscope expect that their input and output data are structured as collections of Key-Value pairs
