HDF5 saving: update with latest proposition from A.Sole
The actual implementation is missing some attributes for an easy introspection by client like silx. Armando recommand to add some extra attributes as "default" on any entry to set the default path to an data set of image. He also propose to correct some mistakes about Nexus attributes and the general organisation:
- create a "default" attribute for the file = entry_0000
- entry_xxx attribute: default = instrument/device_name/data
- entry_xxx/measurement group: NXclass = NXcollection
- entry_xxx/user-name-for-camera group attributes: NXclass = Nxdata, signal = image_data
- /data link to entry_xxx/instrument/device_name/data
- /info link to entry_xxx/instrument/device_name/info
