  Creates an array of elements split into groups the length of `size`.
  If `array` can't be split evenly, the final chunk will be the remaining
  elements.

  @param {Array} array The array to process.
  @param {number} [size=1] The length of each chunk
  @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
  @returns {Array} Returns the new array of chunks.
  @example
  
  _.chunk(['a', 'b', 'c', 'd'], 2);
  // => [['a', 'b'], ['c', 'd']]
  
  _.chunk(['a', 'b', 'c', 'd'], 3);
  // => [['a', 'b', 'c'], ['d']]
