new working program is TP001_logic_v1.pl, older program stupid file 2 is depricated. new working knowledgebase is contain_kb3.kb, old contain_kb and densities_prolog.pl are depricated. plot_scaling.csv is related to hectares of plots, to be used in matlab. The current prolog program is not set to do the stands/all trees, as I am thinking of a more creative way to address this in a parsimonous way.
