Get Value From JSON Pointer

Overview

This transformation takes an object and a json pointer It gets a value out of the object based on the JSON Pointer you give it, otherwise it returns undefined. Since a json file can be nested with a lot of information, the json pointer provides a path through the json to get a value.

This can be compared to a file system (json file), where a path (json pointer) can direct you through a file system to the file you want to open (the value you want returned by the pointer).
