Also refactor ConvertToDiffractionMDWorkspace2 to share common code.

There is still a single unit test failure.

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

The test is not written by me but just decreasing number of test points by two orders of magnitude do works without, seems, affecting the coverage.

workspace to another

It is dirty fix, as because we have allowed adding MDEvents to MDLeanEvents, we have to disable check of the strict workspace types.
This solution should be reconsidered after ticket #7473 is completed.

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

in the case of Workspace2D input. Also more tests

Because this is more thread safe without having to modify all existing code.

Touches nearly everything unfortunately but is necessary.

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

Fixes #3610: MakeDiffractionMDEventWorkspace handles Workspace2D and was tested successfully with WISH data from the SVN.

Fixes #3543: Implemented MDEvent (with runIndex and detectorId). Added factory methods and macros to support it. CreateMDEventWorkspace can create either type of event workspace. Typedefs for MDEventWorkspace3 changed to MDEventWorkspace3Lean etc.

Refs #3023: Removed MAKE_MDEVENTS flag from CMAKE. Made a test helper for MDEvents to reduce code duplication. Refs #2897: No warnings in MDEvents.
