docs: This method is like `_.isMatch` except that it accepts `customizer` which
  is invoked to compare values. If `customizer` returns `undefined`, comparisons
  are handled by the method instead. The `customizer` is invoked with five
  arguments: (objValue, srcValue, index|key, object, source).

  @param {Object} object The object to inspect.
  @param {Object} source The object of property values to match.
  @param {Function} [customizer] The function to customize comparisons.
  @returns {boolean} Returns `true` if `object` is a match, else `false`.
  @example
  
  function isGreeting(value) {
  return /^h(?:i|ello)$/.test(value);
  }
  
  function customizer(objValue, srcValue) {
  if (isGreeting(objValue) && isGreeting(srcValue)) {
  return true;
  }
  }
  
  var object = { 'greeting': 'hello' };
  var source = { 'greeting': 'hi' };
  
  _.isMatchWith(object, source, customizer);
