@MatthiasKillat Seems there is still a problem somewhere:

1. ~~The examples don't run~~ :heavy_check_mark:
2. ~~MemoryProvider_Test.SegmentIdValueAfterCreationIsValid is failing on some builds~~ :heavy_check_mark:

You can have a look if you like. I won't be able to work on it in the next two weeks.

@mossmaurice I will approve after the conflicts are resolved. Please change the move ctor in the follow up PR.
