General settings

	You are allowed to pause the model run and either alter parameter settings under item 1.1.1 or choose a different graphical file that represents the environment (item 1.1.2). By this means the model rund can be made more dynamic.
	Items 1.2.1 - 1.2.3 enable you to adjust the spatial scale of the model. The world width and world length are set to 50m x 50m by default, because the only given example graphical file for the environment has these dimensions. However, a more common setting would be a world size of 100m x 100m. The world height of 50m should be sufficient for all mangrove species. It is not necessary to alter the default setting, though.
	A ground level of 5m (comppare item 1.3) was chosen to enable correct display of the FONs in three dimensions.
	In item 1.4.1 you may set the type of the environment. The available options are of two kinds: The first is to let the program set up an environmental matrix that is uniform or that holds an ascending gradient in x direction. In both cases you can enter the maximum environmental level being used under item 1.4.2. The second is to pass in the environment as a grey-scale graphical file. The "sugarscape.pgm" is an example file, but you can pass in your "own.pgm". As the "sugarscape.pgm" the own pgm-file must be located in the "misc" subfolder of the project directory.
