Changing fruit RGR and making fruit respiration a RGR function
Removing some unused global variables
Changing netcarbon to phloem_balance
Modifying prolleptic firing location on shoot
Changing stem Psk to fixed value (10000) thus allowing CHO to go down to root, needs investigation
Introduced branching angle variation according to relative position from apex
Sylleptic fire according to HSMC

re-enabling fruit growth

Changed respiration
Added dynamic_density for stem
Changed stem Psk_base to fixed value instead of using phloem conductance function (needs further investigation)
Correction to stem storage, needs also to be checked for sometimes storage goes negative

Adding prototyping of respiration function as PythonScripts/respiration.py

back to original WS HSMC
added global variables to do CHO accounting
Corrections and simplifications

Restored all sources and sinks
Reduced all respiration to 25%
Tweeked WS HSMC to get smaller shoot
First year works as expected...

increasing max error allowed
changing needed concentration gradient
trying to get rid of oscillation in Pv. Works when leaf max out storage is more or less fixed to value around 0.02, when higher oscillation are back even though they are in a very small range
Allow 3rd decimal change in leaf SLW in parameter window

Adding docs
Allowing pri.lc.k of leaves to decrease by 0.95 steps if pri.i > gr
Changing alometric relation for leaves area length ratio

First commit after previous code problem
Started from Davis work, changed source and sink functioning
Moved setting of most e and c to update_segment so it is set depending on the previous state of the plant and folding-unfolding process try to find a solution to the system
