503 5081d 09h werner /src/ water cycle: fixed a regression with the calculation of average aging.
added "canopyConductance" as variable for resource units.
added a GUI option to change the current log level.		  
502 5081d 15h werner /src/core/ water cycle for resource units without adult trees; adapted water use for RUs with only few stands by adding "ground cover" up to LAI=1 with default characteristics.  
496 5098d 15h werner /src/core/ changed the behavior of the water-cycle wrt establishment: now the water cycle is executed even if no adult trees are on a resource unit  
484 5101d 13h werner /src/ modified release of memory of trees; QVector::resere() does not actually shrink memory; so now "squeeze()" is used.  
482 5101d 15h werner /src/core/ fixed bug that recruited trees modified the average aging calculation; added some diagnostic code here and there.  
475 5102d 14h werner /src/ * Snag dynamics
debug output "SnagDynamics"
life cycle of Snag objects
include Snag Dynamics in newYear / year end routines

* threadrunner.cpp: parallel execution of species related tasks, e.g. the seed dispersal. In the current form, the ThreadRunner is much nicer:
ThreadRunner runner(mActiveSpecies);
runner.run(func_ptr);		  
461 5108d 08h werner /src/core/ fixed a bug in bookkeeping values from saplings per ru (average height/average age). little refactoring and improvement of code that deals with "SaplingMaps".  
455 5157d 15h werner /src/ changed the layout of the resourceUnitSpecies from a QVector to a QList<ResourceUnitSpecies*>. This seems to be much more appropriate. But caused many small changes throughout the project.  
454 5157d 15h werner /src/ improvements of regeneration/establishment. Looking for bug that stems obviously from copy-constructor problems (resourceUnitSpecies).  
453 5158d 04h werner /src/ sapling growth now in a basic working state. started to implement recruitment. One bug with the "maximum-establishment-height-grid" known.
added also visualization of regeneration layer. Once I have time, I should restructure the drawing/visualization code as it gets quirky (and a paper-concept is available...)		  
452 5158d 10h werner /src/ searching for a bug in the sapling growth....  
451 5158d 13h werner /src/ further development of sapling growth  
450 5158d 15h werner /src/core/ implementing sapling growth...  
438 5212d 10h werner /src/ new GridRunner class to iterate nicely over grids with different sizes.
establishment.cpp: started to integrate the whole regeneration process (including "lazy" calculation of 3pg (only if necessary)).		  
436 5212d 13h werner /src/ climate: added totalRadiation() function
production3pg.cpp: added the calculation of the f_env,yr (total environmental performance of a species)		  
431 5237d 05h werner /src/ included the logLevel-Functions at several locations in the source code.
added a option to only display debug messages in the DebugTimer destructor when elapsed time is longer than one millisecond.		  
376 5277d 15h werner /src/ calculation of an average value for aging at resource unit level.
added variable 'aging' for resource units.
changed comments.		  
370 5284d 13h werner /src/ * expansion of the logwindow on the mainwindow
* bug with multi threading: serialization using QMutexLocker when attempting to write/print the debug outputs.
* enabled painting of the visuals in modelcontroller.cpp (re-enabled??)
* changed the threshold for multi threading to 6 resource-units
* optimized StatData-class to avoid unnecessary calculations of percentiles
* several comments		  
369 5284d 16h werner /src/ * multithreading for 3pg production (crashes)
* do 3PG calculation only if this RU has some leafarea of a species (added clear() functions)
* added GUI-accessible speciesindex-variable for trees		  
367 5284d 17h werner /src/core/ changes in the watercycle.
see http://iland.boku.ac.at/tiki-view_tracker_item.php?itemId=30
the calculation of the effect on the canopy conductance is changed. Now, the combined effects of soil water and vpd response together modify the canopy conductance. In order to do this some structural changes have been necessary. Note: now the response values for vpd and soil water are calculated two times.
