Export/Import instrument states to/from the NSX database file

Ammar Nejati requested to merge writeInstrumentStates into develop

The instrument states are stored in / retrieved from the NSX database under the H5::Group 'DataCollections/dataset-name/Instrument'.

InstrumentStateList is serialized with the following data:

  • detectorOrientation (3x3 matrix)
  • detectorPositionOffset (3d vector)
  • sampleOrientation (quaternion)
  • sampleOrientationOffset (quaternion)
  • samplePosition (3d vector)
  • ni (3d row-vector)
  • wavelength (double-typed scalar)
  • refined (bool-typed scalar)

The HDF5 data are stored compactly as 2d tables; e.g., having S states, the set of detectorOrientation matrices are stored as a single Sx9 table (S rows, 9 columns), where the elements of a each matrix are stored as a single row.

The module core/raw/HDF5TableIO is added to facilitate reading/writing a 2d table as H5::DataSet.

Related DataSet keys are added to DataKeys.h.

Closes issue #398 (closed)
