/**
* Multi User VFS implementation for Horde's database abstraction layer.
*
* Required values for $params:
* - db: A Horde_Db_Adapter object.
*
* Optional values:
* - table: (string) The name of the vfs table in 'database'. Defaults to
* 'horde_muvfs'.
*
* Known Issues:
* Delete is not recusive, so files and folders that used to be in a folder
* that gets deleted live forever in the database, or re-appear when the folder
* is recreated.
* Rename has the same issue, so files are lost if a folder is renamed.
*
* The table structure for the VFS can be created with the horde-db-migrate
* script from the Horde_Db package.
