Putting down carried object when activating another.

[antstubell]

Specifically, I'd like that when player uses a pickaxe to mine ore from a vein (area is almost pitch black) that the torch/lantern they are carrying is put down before the action begins next to where the player is mining. This would provide a light source for the player. When mining is done player can then pick up the torch/lantern. I guess the script would need an OnActivate and GetEquippedItem statement. Help with this please.
