Static storage of an output device and its base (abstract) implementation.
OutputDevices are basically a capsule around an std::ostream, which give a unified access to sockets, files and stdout.
Usually, an application builds as many output devices as needed. Each output device may also be used to save outputs from several sources (several detectors, for example). Building is done using OutputDevice::getDevice() what also parses the given output description in order to decide what kind of an OutputDevice shall be built. OutputDevices are closed via OutputDevice::closeAll(), normally called at the application's end.
Although everything that can be written to a stream can also be written to an OutputDevice, there is special support for XML tags (remembering all open tags to close them at the end). OutputDevices are still lacking support for function pointers with the '<<' operator (no endl, use '
'). The most important method to implement in subclasses is getOStream, the most used part of the interface is the '<<' operator.
The Boolean markers are used rarely and might get removed in future versions.

Creates the device using the output definition stored in the named option.
Creates and returns the device named by the option. Asks whether the option and retrieves the name from the option if so. Optionally the XML header gets written as well. Returns whether a device was created (option was set).
Please note, that we do not have to consider the "application base" herein, because this call is only used to get file names of files referenced within XML-declarations of structures which paths already is aware of the cwd.

Returns the described OutputDevice.
