/**
 * This an implementation of the [visitor pattern](https://en.wikipedia.org/wiki/Visitor_pattern). Pass in an object and it will
 * traverse it using breadth first and call your visitor function once for each node it encounters
 *
 * @param {any} tree The object to crawl
 * @param {Function} visitor The function that will be called for each node. It will receive three parameters: object - the node that was found,
 * name - the name of the node, path - a dot delimited string that indicates depth and membership, depth - indicates how many nodes have been visited
 * level - a integer indicating depth in the object tree,
 * @param {string?} parent Intended to be used when called recursively. It is a dot delimited string that indicates depth and membership
 * @param {number?} depth Intended to be used when called recursively.
 * @param {number?} level Intended to be used when called recursively.
