Description
The SpectraAxis is only useful to ISIS instruments where the spectrum numbers start at 1, whereas the workspace indices must start at 0.
This subclass would be used, e.g., by EventWorkspace. It would be the equivalent of having a simple 1:1 map.

(In [6100]) Refs #1605 and #1595 in a way. Made spectrum numbers and workspace indices match (simple 1:1 map) for EventWorkspaces. Added tracking of detector ID in EVentList. Operators (+) do a union of detector IDs set. SpectraDetectorMap is generated from the EventList detector IDs. Renamed functions to clarify getEventList and getEventListAtWorkspaceIndex. New functions for finalizing the creation of EventWorkspaces. Fixed DiffractionFocussing and ConjoinWorkspaces to use the new functionality - code is made a lot clearer. This work supports Refs #1513 and #1581.

- Status changed from accepted to verify
- Resolution set to wontfix
Changed my mind on this one - See Rev [6100]. Code in EventWorkspace creates a simple 1:1 map which is simpler than subclassing SpectraAxis. Maybe later it could still be done.
Also, the EventWorkspace class should be refactored to use a simple 1:1 workspace index -> spectrumNumber axis.
