re #15286

* Test that BinMD does copy basis vectors so that query can later be made
* Change the rebin mode to use the MDGeometry allBasisNormalized property
* Change the line mode to also use the allBasisNormalized property

This used to be done by copying the experiment info but is handled
separately now that the coordinate is an extra field.

seems all work as expected

and python uncommented

(to be able to commit on another ticket)

to make Histo-workspace accessible from Numpy in a C-way.

This is MD algorithms after all.

If you modify a MDHisto with +, -, * etc. you cannot run BinMD afterwards
because it would work quietly but give incorrect results.

and added counting of events. No test for that part yet

Touches nearly everything unfortunately but is necessary.

by using the ADS::retrieveWS<Type>() method.

Also make doxygen more explicit.

The wrong coordinate transformation was being calculated. Tests happened to pass because the transformation in the previous tests were too simple

and the coordinate transformations to it when binning a MDHistoWorkspace

Refs #4238: Show original coords in sliceViewer
Refs #4191: BinMD can do non-axis-aligned bins on a MDHisto. Works in slice viewer.

AxisAligned + Non-aligned works. Non-Aligned + Non-Aligned does not.

... in SlicingAlgorithm (BinMD, SliceMD) given arbitrary basis vectors.
Specifically for the 3D-3D binning case.
