  @function $file~yaml/get
  @param {string} file - Yaml File to read the value from
  @param {string} keyPath to read (it can read nested keys: `'outerKey/innerKey'` or `'/outerKey/innerKey'`. `null`
  or `'/'` will match all the document). Alternative format: ['outerKey', 'innerKey'].
  @param {Object} [options]
  @param {string} [options.encoding=utf-8] - Encoding used to read the file
  @param {string} [options.default=''] - Default value if key not found
  @returns {string|Number|boolean|Array|Object} Returns the field extracted from the yaml or the default value
  @throws Will throw an error if the path is not a file
