datadir: in, optional, type=string
Set this keyword to the name of the data directory. If not set, the program

file, or the directory directly above it. If it can't find a "data" directory
in either of these two locations, the current directory is used as the "data"
directory. The data directory is ONLY used if there is no "current" last
directory. In other words, it is only used if cgPickfile has not been called
in the current IDL session.
