files are split up in rad and albedo as a stepping stone to draw in Hac modifications. The changes to the code are minimal and restricted to offline building requirements. We should be able to maintain types in offline by using different versions of "cbm".

Following splitting up files, the modifications in HAC were included. The model was modified such that it was no longer bit reproducible.
Further investigation show the first deviation from "bitwise reproducibility".
These plots show that indeed there is no discernible change to the model, which highlights the extreme sensitivity of the quantity surveyed in this respect, "new_sumbal".

The branch linked to #224 actually goes further than what I would like to achieve this Ticket - which is a restructured CABLE that bitwise reproduces the trunk. In all fairness this has to be revised to be "effectively" reproduces the trunk.
Above comment3 links to the first move away from bitwise reproducibility - however shows that there is no discernible corresponding difference in the model output. There is a second such move away from bitwise reproducibility - that also results in zero discernible corresponding difference in the model output. This is due to moving declaration of two variables having KIND=(selected_real_kind) declaration to being simply KIND=REAL.
This is preferable at this stage as the selected_real_kind decs are generally problematic anyway, however LFric intends to employ selected_real_kind in future and this almost guarantees that OUR version of selected_real_kind (r_2) will be even more so (problematic). AND there e is really no need for it - i think.
HOWEVER - as treated here there is NO difference from the trunk. The 2 differences discussed above apply to later implementation which is now addressed in #226.
So what we did was svn co https://trac.nci.org.au/svn/cable/branches/Users/jxs599/HAC/trunkSeptember10.4@6361 T224_JaCed_structure_6361/
169356f0d6b0d5e203baffcdc21d9d217ad7a095 - corresponds to splitting up the files etc but not actually changing anything
svn copy $SVN_CABLE/trunk https://trac.nci.org.au/svn/cable/branches/Users/jxs599/CABLE/Tickets/2019/224
svn co https://trac.nci.org.au/svn/cable/branches/Users/jxs599/CABLE/Tickets/2019/224
/bin/cp -r T224_JaCed_structure_6361/ 224/
we then modified the build process so we could verify that we were't actually changing anything

The quantity "sumbal" changes a few times throughout this process. In all instances there are zero differences observed in the output - as decribed in above comments.
The biggest difference observed can be seen in the Soil moisture. This occurs between revisions 6446 and 6447 when we switch between sections of code appropriate to sunlit processes triggering off the zenith angle rather than downward shortwave. Even so, the differences are minor.
