Detailed Description

Abstract FITS extension base class.

This class defines the abstract interface for a FITS extension, also known as Header Data Unit (HDU). Each HDU consists of a header and a data area. The header is composed of cards and is implemented by the GFitsHeader class. The data are is either an image or a table which are implemented as derived classes from GFitsHDU.

Todo:: Implement GFitsHDU* select(const std::string& expr) that applies to a table HDU for row selection.
