469 5112d 20h werner / update contains some fixes in regeneration/sapling growth model.
contains also a beta-version of the snag dynamics sub module.		  
468 5113d 02h werner /src/ starting the implementation of the snag dynamics submodule.
New class: Snag
added Snag to ResourceUnitSpecies
added links to Snag in Tree		  
462 5113d 20h werner /src/core/ if a sapling of a species is already present at a specific location (i.e.: pixel), than no other cohort of that species can regenerate on that pixel.
new function: hasSaplingAt().		  
454 5163d 05h werner /src/ improvements of regeneration/establishment. Looking for bug that stems obviously from copy-constructor problems (resourceUnitSpecies).  
453 5163d 19h 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...)		  
451 5164d 03h werner /src/ further development of sapling growth  
450 5164d 05h werner /src/core/ implementing sapling growth...  
449 5164d 06h werner /src/ start of implementation of sapling growth.
setup of the temporal height-map for saplings.		  
440 5217d 04h werner /src/core/ climate: added a pre-calculated value for the 10.5hrs day
including establishment calculation in the normal execution path.		  
438 5218d 00h 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)).		  
376 5283d 06h werner /src/ calculation of an average value for aging at resource unit level.
added variable 'aging' for resource units.
changed comments.		  
370 5290d 04h 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 5290d 07h 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 5290d 08h 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.		  
278 5466d 12h werner /src/ Management output. Added a statisticsMgmt() for ResourceUnitSpecies. Complicated to get the order right.  
277 5466d 17h werner /src/ added "Gesamtwuchsleistung" i.e. total growth.  
262 5470d 20h werner /src/ added output for dead trees (StandDeadOut)  
234 5477d 14h werner /src/core/ added (during dev. of watercycle) new properties: area() to ResourceUnit, leafArea() to Tree, added LAI-counting to StandStatistics.  
230 5478d 12h werner /src/ 3PG work out  
229 5478d 14h werner /src/ 3pg model. fixed a problem with the setup of ResourceUnitSpecies (a classic: a pointer to a vector, which is still growing... grrrrr.... it took hours to find)
