ConvertToReflectometryQ producing MatrixWorkspaces

[Owen Arnold]

This is a request from Tim Charlton to provide additional features around the ConvertToReflectometryQ functionality. The ConvertToReflectometryQ Algorithm is correctly working and producing multidimensional outputs with Q components correctly resolved and plotted along each axis. However, there are two problems that would be solved by providing flexibility of the output workspace type.

• The reflectometry group users are much happier working with Matrix Workspaces, and there is some frustration when other workspace types are thrown into the mix.
• MDWorkspace algorithms only support centre point binning, where-as fractional binning would be possible (via Rebin2D) if the output workspaces were of type Workspace2D.

I'll implement this as additional functionality to ConvertToReflectometryQ, as this is what Tim originally requested. I didn't think that it would be possible, to do this at first, without making the algorithm really clunky, but most of the functionality can go in the various ReflectometryTransform types, and the output workspace can be made to be of type IMDWorkspace (so handling both Matrix and MDWorkpspaces as outputs).

Important to have this implemented before the end of iteration 2.6!

refs #7445. Rename execution method to executeMD.

Also enable tests that seem to have been disabled, or removed in CMake.

refs #7445. Hide MD Specific features of transforms.

Make it so that the same transform types make sense for md and non-md transformations. This means moving some details concerned with the output type out of the constructors.

refs #7445. Create QxQz Matrix WS Transform.

Add unit tests to cover the new case. Ensure that the experiment info is copied across, and add new property that allows the user to select what output type they want. The output type defaults to the existing MDWorkspace return as this will ensure backwards compatibility.

Tester: I know the MDWorkspace options are producing the right results, so I can expect to see the same colour fill plot if I compare the new 2D workspaces against the MD workspaces outputs, all other things being equal. I have created the attached script for you, which will do this. Each of the comparision options compares the outputs via running the algorithm in MD-mode (and then rebinning via BinMD to a regular histo workspace) and the 2D workspace ouput.

A visual inspection of the generated plots should demonstrate that the new outputs are as close to the original md outputs as is practically possible.

It works correctly. Thanks for the script for testing :)
