Detailed Description

Helper class that provides file on construction and cleans up on destruction.

Caution: There's no synchronisation between multiple FileProvider instances, that provide the same file from the same media. If the first one goes out of scope, the file is cleaned. It's just a convenience for 'access and forgett'.

Caution: We should either store the reference MediaAccess' MediaHandler here (for this MediaHandler must become a ref counting pointer class), or we need more info from MediaHandler (whether he's downloading to the local fs. If not, no releasefile is necessary). Currently we can not releaseFile after the media was closed (it's passed to the handler, which is deleted on close).
