Torsten Ruger 696886cc94 remove Data2 in favour of Data4
as we write a Marker, type and marker make up 2
so data2 is just the type, not useful

# Integer class for representing maths on Integers
# Integers are Objects, specifically DataObjects
# - they have fixed value
# - they are immutable
# (both by implementation, not design.
# Ie it would be possible to change the value, we just don't support that)
