Since we have put PeakShape in Geometry, SpecialCoordinateSystem must be moved to the Kernel package out of API.

The converted text is stored in separate .rst files in the docs directory.

for ConvertToDiffractionMDWorkspace

and verified that everything (unit tests) works fine, so we have two identical versions of the same algorithm with only the version number different

into MD algorithms

refs #5537 Renamed couple of classes responsible for event conversion

These were highlighted by running the LoadLiveData unit test.
They won't affect the situation that led to the creation of this ticket
as they're MD-related and my test run wasn't.

to get reasonably fast results both on small and large workspaces

because the ConvertToDiffractionMDWorkspace algo does not modify the input, it applies the lorentz correction on the fly.

for TOPAZ_5625 (down from 109 seconds before split change). FIFO is a lot more efficient than the largest cost scheduler for lots of small tasks

for a large-ish event file, by splitting more frequently.
Also refs #4800 parallel binnining in SliceViewer dynamic rebinning

in the case of Workspace2D input. Also more tests

also fix for TestViewer

disabling it. Also wiki docs

for code reuse from ConvertToEventWorkspace

Touches nearly everything unfortunately but is necessary.
