Common Script External Code

This is a list of the external code that is available inside all scripts - variables, functions, and classes that "magically" exist.

This list is pulled from the ~/Documents/Wolfire/Overgrowth/ directory, from the aschar_docs.h and aslevel_docs.h files, which are automatically generated by the game.

See this page to find the location for the Wolfire/Overgrowth folder on each OS - http://wiki.wolfire.com/index.php/How_to_clear_the_game's_cache

TODO: These can be documented individually, possibly on their own pages

TODO: Provide different groupings as well? Might be fine to duplicate them into feature sections of this page or another page.
