Allow dimension configuration for Event Nexus Reader

[Owen Arnold]

Dimension properties are currently hard-coded for this reader. We already have widgets that can do this sort of configuration, but in order to use them geometry xml must be obtained from imddimension types. Currently generation of the xml is the responsibility of the MDGeometry type, which is not used for event-based visualisation.

1) Extract the geometry xml logic from MDGeometry 2) Enable dimensional configuration for vtkEventNexusReader

(In [11356]) re #2995 Refactoring. Pull out xml creation from geometry so that it can be used elsewhere.

(In [11544]) re #2995. Dimension configuration now similar to that for non-event based rebinning cutting. Note: sorry for size of commit, have not been able to get work into SVN owing to server build problems.

[Owen Arnold]

(In [11786]) re #2995. Enforce rule that mapped dimensions cannot be integrated. In order to be integrated, they must be recorded as Ordinary dimensions only (not aligned to x, y, z, t). This cannot be done at the IMDWorkspace + IDMDimension levels, so delegated to Parsing. Rule is switchable at compile time. Next step is to have Qt widgets respect this rule too.

(In [11788]) re #2995. Fixes test macro usage.

(In [11793]) re #2995. Prevent nbins == 1 on mapped dimensions via dimension widget.

[Owen Arnold]

(In [11795]) re #2995. Because Event-based rebinning can use ImplicitFunctions and MD-CPR cannot. With MD-CPR axis aligned cuts are very important and must be syncronised with Box selector. We therefore prevent this happening by disabling dimensions limit selection for MD-CPR type filters.

[Owen Arnold]

(In [11841]) re #2995. Switch dimension between integrated/non-integrated in the GUI. This is incompletely hooked-up. Actually a good deal of logic is needed to keep perfect synchronisation between non-integrated/integrated dimensions behind the scenes. This will come next.

[Owen Arnold]

(In [12075]) re #2995. Move to MVP design. Avoid smart-widget type QT widgets. Synchronisation logic introduced for moving between integrated and non-integrated dimensions.

[Owen Arnold]

(In [12093]) re #2995. Multidimensional rebinning should now make ubiqutious use of vtkDataSetFactories via getSignalNormalizedAt

[Owen Arnold]

(In [12094]) re #2995. Minor fix. Scope resolution error in header.

[Owen Arnold]

(In [12159]) re #2995. fix TODO. Improve test coverage.

[Janik Zikovsky]

I've used this.
