move parfait into register

register layer uses parfait models to generate object space
so parfait  should be part of register (not above it)

+# A List, or rather an ordered list, is just that, a list of items.
+
+# For a programmer this may be a little strange as this new start goes with trying to break old
+# bad habits. A List would be an array in some languages, but list is a better name, closer to
+# common language.
+# Another habit is to start a list from 0. This is "just" programmers lazyness, as it goes
+# with the standard c implementation. But it bends the mind, and in oo we aim not to.
+# If you have a list of three items, you they will be first, second and third, ie 1,2,3
+#
+# For the implementation we use Objects memory which is index addressable
+# But, objects are also lists where indexes start with 1, except 1 is taken for the Layout
+# so all incoming/outgoing indexes have to be shifted one up/down
