PdfMetadata class

Metadata extracted from the PDF Info dictionary.

All fields are nullable; a null value means the field was not present in the Info dictionary (as opposed to being present but empty). This mirrors the PDF specification where field presence and field value are distinct states.

The eight standard Info dictionary fields are: title, author, subject, keywords, creator, producer, creationDate, and modDate.
