Class FitsLineAppender
java.lang.Object
nom.tam.fits.utilities.FitsLineAppender
This class handles the writing of a card line. It keeps track of the position
in the line and will limit it to 80 characters. A write will never cross the
line border but a write when the line is at position 80 will start a new
line.
