move parfait into register

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

+# Class is mainly a list of methods with a name (for now)
+# The memory layout of object is seperated into Layout

+# A class describes the capabilities of a group of objects, ie what data it has
+# and functions it responds to.
+#
+
+# So it is essential that the class (the object defining the class)
+# can carry methods. It does so as instance variables.
+# In fact this property is implemented in the Layout, as methods
+# may be added to any object at run-time

+# An Object carries the data for the instance variables it has
+# The Layout lists the names of the instance variables
+# The class keeps a list of instance methods, these have a name and code
