Fixes a bug when plotting 2D data using the tab10 qualitative color map.
Adds a __lt__ function to the NXobject class to allow sorting by object name. This prevents exceptions when, for example, zipping identical keys with NXobject instances.
Adds context manager functions to the NXroot class, so that they can be opened with a similar syntax to the standard Python open context manager. For this reason, nxopen has been added as an alias to nxload.
