<description>Directory type. Is used to manage directories and their content (not restricted to the project folder).
How to iterate through the files of a directory example:

var d = Directory.new()
if d.open( path )==0:
d.list_dir_begin()
var file_name = d.get_next()
while(file_name!=""):
if d.current_is_dir():
print("Is directory: " + file_name)
else:
print("Is File:" + file_name)
file_name = d.get_next()
else:
print("Some open Error, maybe directory not found?")
