/**
|
|
* This method is like `_.sortBy` except that it can sort by multiple iteratees
|
|
* or property names.
|
|
*
|
|
* If a property name is provided for an iteratee the created `_.property`
|
|
* style callback returns the property value of the given element.
|
|
*
|
|
* If an object is provided for an iteratee the created `_.matches` style
|
|
* callback returns `true` for elements that have the properties of the given
|
|
* object, else `false`.
