Currently, dealing with trees in forested areas can be difficult and improper execution can result in floating trees or leaves that won't decay due to nearby logs. It would be very convenient to have a function that, when called on a particular coordinate, detects and cleanly removes the tree.
Caution may be taken not to remove e.g. wooden support pillars (from mineshafts etc.).
Depending on the type of tree (e.g. Acacia), further steps may need to be taken to effectively remove the tree.
