/**
\ingroup io
\brief temporary data storage to avoid storing on disk
This class implements a data storage pool as a singelton
that can be used to store some
data temporarly like if it would be stored on disk.
Each IO plugin automatically defines an interface to store in and load
from this pool. The extension, by which this behaviour is triggered is ".@".
\todo add delete key function,
\todo add automatic key generation
\todo (maybe) all plugins that load data should load to the pool first to enable
loading from temporarly generated data
