This tool allows stepping through a series of files using a movie file
name template. It is normally loaded from the Movie List tool. The
file name template can be manually changed to whatever desired. So can
the numerical ranges.

A valid movie series is a set of files with a number as part
of the name. The "file name template" text box should contain
the name with pound signs (#'s) where the digits in the number
would normally be. If the numeric field is of fixed width, the
number of # signs must equal this width, otherwise use a single
# sigh for variable width. The numerical range is then entered
in the 2 range boxes, htting return after each one to make it
actually update. Once this is done, the slider labeled
"image # selection" can be used to select any image in the series.
Moving the slider will cause the header (if any) to be displayed
in the file inspector. To display a given file, hit the red
"display selection" button. There are also buttons for stepping
up and down the series and the increment of the step can be changed
from 1 to a larger value. This is useful for quickly scanning through
a data series.
