Class for storing ordered metadata with comments.
This class stores key/value pairs like PropertySet, of which it is a subclass. The difference is that the PropertyList maintains the order of the key/value pairs according to how they were inserted. By default, replacing the value of an existing key does not change its ordering. In addition, a comment string may be associated with each key/value pair.
The main motivating use case for PropertyList is FITS headers.
PropertyLists are not truly hierarchical, although they accept dotted paths as keys. If a PropertySet or PropertyList is added as a value to a PropertyList, the hierarchical pathnames are flattened into the resulting PropertyList.
