Generic Encounter Table for Pathfinder

I came up with a generic encounter table for Pathfinder (or for any 3.x d20 game, really) that takes into account the "safety" of an area. "Safe" areas are less likely to produce high-CR encounters, while dangerous areas are more likely. The specific encounter in question should be determined by the DM, taking into account terrain and the indicated CR.
