502 5117d 07h 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 5134d 07h 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 5137d 06h werner /src/ modified release of memory of trees; QVector::resere() does not actually shrink memory; so now "squeeze()" is used.  
482 5137d 07h werner /src/core/ fixed bug that recruited trees modified the average aging calculation; added some diagnostic code here and there.  
475 5138d 06h 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 5144d 01h 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 5193d 07h 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 5193d 07h werner /src/ improvements of regeneration/establishment. Looking for bug that stems obviously from copy-constructor problems (resourceUnitSpecies).  
453 5193d 21h 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 5194d 02h werner /src/ searching for a bug in the sapling growth....  
451 5194d 05h werner /src/ further development of sapling growth  
450 5194d 07h werner /src/core/ implementing sapling growth...  
438 5248d 02h 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 5248d 05h werner /src/ climate: added totalRadiation() function
production3pg.cpp: added the calculation of the f_env,yr (total environmental performance of a species)		  
431 5272d 21h 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 5313d 08h werner /src/ calculation of an average value for aging at resource unit level.
added variable 'aging' for resource units.
changed comments.		  
370 5320d 06h 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 5320d 09h 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 5320d 10h 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.		  
331 5450d 20h werner / changed order in which statistics are calculated: statistics of species and RUs are now cleared immediately before they are refilled (during the growth of individual trees). Now steps between (e.g. water-cycle) can access valid statistics (that are essentially the state of the end of the last year)
