  Coding Problem #2
  Write a method, `findRecord`, that will take an object collection, `records`

  matches the id of a record in the collection and throw an error message if the
  record id was not found

/*
  Coding Problem #3
  Write a method, `searchRecords`, that will take an object, `node`, a string, `key`,
  and string, `term`.
  The method should travers the tree to find all related nodes where `term` matches
  the `node`'s property for the given `key`.
  The original `node` should be considered immutable
  Additional Info:
  - `node` is expected to be a "node tree"
  - The `node` will have an imbedded object collection, `children`, that is a collection
    of nodes

  Example "node tree" object:
  {
    id: 1,
    name: 'Menu',
    description: 'Our super awesome food menu',
    children: []
  }
  Example of Search Results:
  term: 'Fr'
  key:name 
  Results: (simplified)
  - Menu
  |-- Combo #1
  | |-- French Fries
  |-- Combo #2
  | |-- Frozen Dairy Product
  |-- French Fries
  |-- Fresh Fruit
  |-- Frozen Dairy Product

  Coding Problem #4
  Write a method, `getRecords`, that will take a string, `recordType`, and an optional

  The method should query an API and return the result set for `recordType`

  Requirements:
  - Must use Promises or `async/await`
  - Must use JSONPlaceholder as your API, https://jsonplaceholder.typicode.com/.

  Challenge Question
  Using the IMBD API create an API and UI in your favorite language(s) that would allow
  one to search movies, directors, actors, and IMBD votes.
  Notes:
  - Use http://theimdbapi.org/ or your favorite API for IMDB
  Requirements:
  The UI MUST:
  - be searchable by Title, Director, Actor, IMDB id,
  - pagination
  - detail view for Movie, Actor, Director.
  - sortable by Title, Director, Actor, IMBD likes.

  Bonus Question, Seven Degrees of Kevin Bacon...
  Using the IMDB

  Include a Page that would allow for user it select an actor and see their "degrees"
