PropertyList should support missing values and possibly units

      Description

      PropertyList is how we perform FITS header I/O, but it does not support missing values, which are used in FITS headers to indicate items that have unknown value.

      Furthermore, it would be nice to have support for units as a separate field, though for FITS headers one must include that information as part of the comment.

      I am not necessarily proposing to do this work, but I felt I could at least get permission for it to be done.

            Description PropertyList is how we perform FITS header I/O, but it is missing two important features for FITS files:
            - It does not support comments
            - It does not support missing values (which are in FITS headers used to indicate items that have unknown value).

            Furthermore, it would be nice to have support for units.

            I further propose that PropertySet gain support for comments and units (and missing values if practical, to keep the differences between PropertyList and PropertySet small).

            I am not necessarily proposing to do this work, but I felt I could at least get permission for it to be done.             		PropertyList is how we perform FITS header I/O, but it does not support missing values, which are used in FITS headers to indicate items that have unknown value.
