Export Tango Device Data to .json files

To export device properties to a .json file:

> python -c "\
import json,fandango;
d,f = 'bl00/ct/eps-plc-01','bl00.albaplc.json';
props = fandango.tango.get_matching.device_properties(d,'*');
fandango.dict2json(props,filename=f);
"

To export all device data (attribute config and values, command definition, ...):

> python -c "\
import json,fandango;
d,f = 'bl00/ct/eps-plc-01','bl00.albaplc.json';
fandango.dict2json(fandango.tango.export_device_to_dict(d),filename=f);
"

Or just:

> fandango.sh "dict2json(export_device_to_dict('bl00/ct/eps-plc-01'),'bl00-albaplc.json')
