ScanRecorder (ALBA specific)

The production of the output files can be crontrolled by the environment variable ScanRecorder. It can have values like FIO_FileRecorder, SPEC_FileRecorder or NXS_FileRecorder or a list of recorder names. This feature takes the NeXus integration at Alba into account. It does not apply to DESY where the recorders are selected by the extension of the output files.
