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

(should be unit tests for that particular case)

It is pain to have BC shared pointer in Nexus loader. It is also question if it needs access to box controller at all. This is why it is currently accessed through const pointer

enabled its test and fixed (I believe unnoticed earlier) errors with file-backed operations.

It may be not very efficient file mode as one needs to identify the if the buffer for SaveMD make file based is defined correctly.

only MDBoxFlatTree may still need to be modified for this ticket.

Temporary Reverted box controller to with control of boxes to change to vanilla box controller and disabling BC copy constructor, as it is too complex for file based workspaces.

small changes to algorithms too to incorporate new logic of working

into Kernel

Add new method on IMDWorkspace to get any special coordinate system settings. On concrete implementations add setters. Add tests for setters and default values.

and enabling corresponding tests

The volume calculations rearranged in the way to decrease the round-off errors. Intermediate volume calculations in copy constructor have been disabled.
