/**
 * Wave Framework <http://github.com/kristovaher/Wave-Framework>
 * Filesystem Cleaner
 *
 * This script is used to clear Wave Framework system generated filesystem. It should be used 
 * for debugging purposes during development or for maintenance once system is deployed. This 
 * script can be configured by running it with a GET variable. Possible values are 'maintenance' 
 * (clears only cache and temporary files), 'all' (clears everything), 'output' (clears output 
 * cache), 'images' (clears images cache), 'resources' (clears cache of JavaScript and CSS), 
 * 'custom' (clears custom cache), 'tags' (clears cache tags), 'messenger' (clears State Messenger 
 * data), 'errors' (clears debugging errors), 'limiter' (clears request data of user agent IP's), 
 * 'logs' (clears system logs), 'tokens' (clears API session tokens), 'tmp' (clears folder from 
 * everything that might be stored here), 'data' (clears the folder intended for database 
 * storage), 'backups' and 'updates' (clears folders that store backup and update archives) 
 * and 'userdata' (entirely custom storage folder). Please make sure to use 'all' carefully, 
 * since it might remove sensitive data. The script runs in 'maintenance' mode by default.
