Written in BASH script, and should be made executable and by default should be
in the same directory of the 'pg2d' program it requires.

It calls 'pg2d' to make a PNG plot output of each fits file in a list that it
is given as its single argument.  This list should include the PATH to those
files as well.

It can be generated for an entire directory by:
	ls /PATH/TO/DIRECTORY/*.fits > listfile

or you could of course use a wildcard to select a subset of files as well.
Make sure to specify the *.fits part to avoid ls searching down into
subdirectories.

You must change any of the options to 'pg2d' on line 36.  See the README.PG2D
document for all the options that are possible.

It puts the resulting PNG files in a subdirectory of the path to the files
surprisingly called 'png'.  It also makes a subdirectory called 'movie' and
copies the movie parameter file into it so the next step of making the movie is
easier.  If the 'png' directory already exists, IT WILL BE DELETED to avoid
confusion when generating the movie.  The 'movie' directory is left untouched,
but any changes to the movie.par file within it will be lost.
