C4996. Warning that std::shared_ptr::unique() has been deprecated
Added a suppression to the MSVCSetup.cmake file. This is a bit of
a stop gap while an alternative solution is investigated

C4250. Warning that Algorithm and all the derived classes inherit
various methods "by dominance"
PropertyManagerOwner has been added to the Algorithm class by composition
instead of by inheritance which removes the diamond

Lots of instances of IAlgorithm_sptr type have been replaced with
"auto" to provide some extra flexibility around the arrangement of
the class\interface hierarchy in future

Also remove a couple of references to PropertyManagerOwner in case
its removed in future (merged into Algorithm)
