docs: Creates a shallow clone of `object` excluding the specified properties.
  Property names may be specified as individual arguments or as arrays of
  property names. If a callback is provided it will be executed for each
  property of `object` omitting the properties the callback returns truey
  for. The callback is bound to `thisArg` and invoked with three arguments;
  (value, key, object).

  @param {Object} object The source object.
  @param {Function|...string|string[]} [callback] The properties to omit or the

  @param {*} [thisArg] The `this` binding of `callback`.
  @returns {Object} Returns an object without the omitted properties.
  @example
  
  _.omit({ 'name': 'fred', 'age': 40 }, 'age');
  // => { 'name': 'fred' }
  
  _.omit({ 'name': 'fred', 'age': 40 }, function(value) {
  return typeof value == 'number';
  });
  // => { 'name': 'fred' }
