fixed *big* regeneration bug. The map with the height of saplings on a resource unit was used in the establishment subroutine although it was *invalid*. Now the establishment and the regeneration are (again?) in one function and use the same valid map.
this removed the strange stripes in the regeneration pattern (there should have been crashes, but weren't). Consequently, the performance debug output was modified.
added better formatting to debugtimer.cpp for large times (in hours, minutes, seconds). |

changed establishment: now (after some discussion), we use two random numbers and "emulate" the multiplication ( seed x biotic x abiotic ). First we select choose for 20m seed pixels a random number for abiotic environment (abiotic), and if ok for every 2x2m pixel (biotic x seed). This split is a huge performance improvement, but leads probably to more "pixels" in the 20m resolution. First tests do not show those effects, though. |

added a "randomGenerator" - function to the resource unit -> this should be used when fetching random numbers from within functions that are executed in a multi-threaded way. You could also use GlobalSettings::instance()->randomGenerator(). |

problems with multihtreading and the random generator. Crashes revealed that the MersenneTwister class is not multithreadable; The solution now is to have for each Thread in the thread pool one random number generator. This removes the crashes, but makes changes to the code necessary. |
