class DrupalExtensionNamespaceFinderPlugin in X Autoload 7.4

- 7.5 src/ClassFinder/Plugin/DrupalExtensionNamespaceFinderPlugin.php \Drupal\xautoload\ClassFinder\Plugin\DrupalExtensionNamespaceFinderPlugin
There are different dimensions of state for each module:
1) Classes outside of Drupal\\$modulename\\Tests\\ a) We don't know yet whether these classes are using PSR-0, PSR-4, PEAR-Flat, or none of these. b) We know these classes use PSR-0 only. c) We know these classes use PSR-4 only. d) We know these classes use PEAR-Flat only.
2) Classes inside Drupal\\$modulename\\Tests\\ a) We don't know yet whether these classes are using PSR-0, PSR-4, or none of these. b) We know these classes all use PSR-0. c) We know these classes all use PSR-4.
Any combination of a state from (1) with a state from (2) is possible.
The state could even change during the execution of the findClass() method, due to another autoloader instance being fired during a file inclusion, e.g. for a base class.
