Python WorkspaceProperty for WorkspaceGroups

[Vickie Lynch]

When I used WorkspaceProperty in the declareProperty line of a python algorithm with the new api, the input workspace was changed from the WorkspaceGroup to a workspace inside the group. See algorithm, SortByQvectors with attached input.

[Martyn Gigg]

So this is the expected behaviour. The default behaviour when given a group is to simply call the algorithm sequentially for each member of the group in turn, so that is what is being seen here.

I will accept though that an algorithm may want to mandate the input as a group, which is possible in C++ using WorkspaceProperty<WorkspaceGroup>. This is not possible in Python so a WorkspaceGroupProperty should be added to keep in step with C++.

Don't unroll groups if property is WorkspaceProperty<WorkspaceGroup>

as this type indicates that the request is for the input to be the whole group. Refs #6603

Tester: Use the attached example algorithm and script below to confirm that you can pass a group into a Python algorithm as a whole, rather than it being unrolled. The algorithm simple logs the types of each workspace.

not_group = Load("LOQ49886.nxs")

agroup = Load("CSP78173.raw")
TestWorkspaceGroupProperty(agroup,not_group)

The script reports the correct types for the workspaces.
