During the last months, a lot of gradual changes to policies and guidelines
had been finalised and documented. Moreover, recent clarifications regarding
memory management in the render engine will lead to a clearer definition
of the »Vault« Layer's role, with some ''engine code'' expected to move down.
On this occasion, I reworked relevant sections in the documentation to
confirm the role that now falls to central parts of the overall architecture.
Notably I decided to rename those parts related to the application backbone
as »Vessel« — to underpin the more active and defining role they assumed.
the buildsystem will now pick up and link
all test cases according to the layer, e.g.
backend tests will automatically be linked
against the backend + library solely.
