#1418 Aggregate several commits together... to get one that actually compile! There was an issue of includes not put properly at the right time in the repository, and also the fact I moved from Seldon to Xtensor but Jerome worked (rightfully) on top of previous master. Most of the content of the resulting commit is Jerome's, except the ppart related to Xtensor.

Below I put the text of the original commits:

1 - PartialSpecialization for the new Microsphere model used for the InternalVariablePolicy.
2 - Moved MicrospherePolicy dependencies into the CoreLibrary.
3 - Parameter description updated.
4 - Update XCode project: during rebasing with main branch, there were conflicts that were solved by keeping this main branch project; new files have been properly added in this commit.
