/**
 * A Bru file is made up of blocks.
 * There are three types of blocks
 *
 * 1. Dictionary Blocks - These are blocks that have key value pairs
 * ex:
 *  headers {
 *   content-type: application/json
 *  }
 *
 * 2. Text Blocks - These are blocks that have text
 * ex:
 * body:json {
 *  {
 *   "username": "John Nash",
 *   "password": "governingdynamics
 *  }

 * 3. List Blocks - These are blocks that have a list of items
 * ex:
 *  tags [
 *   regression
 *   smoke-test
 *  ]
