public class NXcontainerImpl
extends NXobjectImpl
implements NXcontainer
State of a container holding the sample under investigation.
 A container is any object in the beam path which absorbs the beam and
 whose contribution to the overall attenuation/scattering needs to be
 determined to process the experimental data. Examples of containers
 include glass capillary tubes, vanadium cans, windows in furnaces or
 diamonds in a Diamond Anvil Cell. The following figures show a complex
 example of a container:
 .. figure:: container/ComplexExampleContainer.png
 A hypothetical capillary furnace. The beam passes from left to right
 (blue dashes), passing through window 1, then window 2, before
 passing through the downstream wall of the capillary. It is then
 scattered by the sample with scattered beams passing through the
 upstream wall of the capillary, then windows 4 and 5. As part of the
 corrections for a PDF experiment it is necessary to subtract the PDF
 of the empty container (i.e. each of the windows and the capillary).
 To calculate the PDF of the empty container it is necessary to have
 the measured scattering data and to know the nature (e.g. density,
 elemental composition, etc.) of the portion of the container which
 the beam passed through.
 .. figure:: container/ComplexContainerBeampath.png
 A complete description of the shapes of the container elements with
 their orientation relative to the beam and also information on
 whether they are upstream or downstream of the sample is also
 therefore important. For example, although the windows 2 and 4 have
 the same shape, the path taken through them by the beam is very
 different and this needs to be modelled. Furthermore, it is not
 inconceivable that windows might move during an experiment and thus
 the changes to the beampath would need to be accounted for.
 This class encodes the position of the container with respect to the
 sample and allows the calculation of the beampath through the container.
 It also includes sufficient data to model beam absorption of the
 container and a link to a dataset containing a measurement of the
 container with nothing inside, to allow data corrections (at a specific
 beam energy/measurement time) to be made.
