If you have V5.4 you can use FILE_TEST( /DIR) to test if  a directory
exists, and FILE_MKDIR to create a directory.     If you have an earlier
IDL version you can try to CD to the directory and catch any errors (as
in  http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/system/is_dir.pro)
and SPAWN to create a directory.
