Update the auto_loader class to use an include statement on each file in the project to load the class within the file. This will allow mismatched names within the file to be loaded and mapped according to the declaration instead of the filename. The class is then checked against the parsed classes from the PHP engine so that namespaces are available and mapped to the file they were declared in. An update was also made to the search algorithm used to find a file that was not already loaded by collapsing the array to have only valid matches to increase performance on a cache miss. Logging within the auto_loader has been moved to a function.
Multiple files were modified to allow the include statement. When the class has the `if(class_exists())` statement, the auto_loader is called to check for the class. This caused an infinite loop scenario so all wrappers have been removed. The auto_loader will now break the loop by directly modifying the internal classes array instead of trying to restart with the 'reload_classes' method.
- APCu is used to cache classes so any loading of the classes is done only once. To clear the APCu cache, restart php-fpm or call the auto_loader::clear_cache() function.
- Cache file is used when APCu is not available. To clear the cache remove it from the tmp folder or call the auto_loader::clear_cache() function.
- All classes must no longer have a class_exists wrapper to benefit from the performance boost.
- Classes should not be directly included when the auto_loader is used.
