/**
* Performs an array_pop() on a source array.
*
* @MigrateProcessPlugin(
* id = "array_pop",
* handle_multiples = TRUE
* )
*
* The "extract" plugin in core can extract array values when indexes are
* already known. This plugin helps extract the last value in an array by
* performing a "pop" operation.
*
* Example: Say, the migration source has an associative array of names in
* a property called "authors" and the keys in the array can vary, you
* can extract the last value like this:
*
* @code
* last_author:
* plugin: array_pop
* source: authors
* @endcode
