/**
* Class for abstraction of filesystem functions
* This class won't call any filesystem functions for itself but but will pass them to the correct OC_Filestorage object
* this class should also handle all the file permission related stuff
*
* Hooks provided:
* read(path)
* write(path, &run)
* post_write(path)
* create(path, &run) (when a file is created, both create and write will be emitted in that order)
* post_create(path)
* delete(path, &run)
* post_delete(path)
* rename(oldpath,newpath, &run)
* post_rename(oldpath,newpath)
* copy(oldpath,newpath, &run) (if the newpath doesn't exists yes, copy, create and write will be emitted in that order)
* post_rename(oldpath,newpath)
* post_initMountPoints(user, user_dir)
*
* the &run parameter can be set to false to prevent the operation from occurring
