Use CutMD in the VSI

[OwenArnold]

see original ticket here

tester The cutmd option should work in a similar way to the existing binmd and slicemd options. Original behaviour for those options should be unchanged.

1. Load the MDEvent_Osiris dataset
2. Run this in MantidPlot

p = Projection()
p.u = [1,1,0]
p.v = [-1,1,0]
p.createWorkspace('proj')

3. Load the MDEventWorkspace in the VSI
4. Rebin the Workspace via CutMD just set the first 3 entries to be 0.1 and the 4th to be 1. Leave projection blank. Set cube axis shown.
5. Unbin
6. Do the same as 4 but set the projection to be proj. You will see that the data has been rotated 45 degrees.

Following the test instructions produces the expected results.

Additional testing:

• CutMD with filters: works
• Switch from CutMD to BinMD and vice versa: works
• Switch from CutMD to SliceMD and vice versa: works
• Can insert values into bin5: error given out by logger
• Using different values: Error parsing Basis\Vector3 parameter: Number of bins for output dimension 3 should be >=1
