/*! \class Keyword

        \brief Abstract base class defining the interface for Keyword objects.

        Keyword object creation is normally performed inside FITS constructors or
        FITS::read, HDU::readKey, and HDU::addKey functions.  Output is performed
        in HDU::addKey functions and Keyword::setValue.

        Keywords consists of a name, a value and a comment field. Concrete templated
        subclasses, KeyData<T>,  have a data member that holds the value of keyword.

        Typically, the mandatory keywords for a given HDU type are not stored as
        object of type Keyword, but as intrinsic data types. The Keyword hierarchy
        is used to store user-supplied information.

*/

/*!  \fn Keyword::Keyword (const String &keyname, ValueType keytype, HDU* p, const String &comment = "");

      \brief Keyword constructor. 

      This is the common behavior of Keywords of any type. Constructor is protected 
      as the class is abstract.

*/

/* \fn friend ostream& operator << (ostream &s, const Keyword &right);

        \brief left in for historical reasons, this seldom needs to be called by users

        This writes the Keyword to the file, and is called internally during HDU::addKey
        operations or the Keyword::setValue function.  It shouldn't normally need to be
        called explicitly. 
*/

        \brief return a pointer to the FITS file containing the parent HDU.

/*!  \fn template <typename T> T& Keyword::value(T& val) const
       \brief get the keyword value

       \param val (T) Will be filled with the keyword value, and is also the function return value.

       <b>Allowed T types:</b> CCfits stores keyword values of type U in a templated subclass of
       Keyword, <b>KeyData<U></b>.  Normally U is set when reading the Keyword in from the file, 
       and is limited to types int, double, string, bool, and complex<float>.
       (The exception is when the user has created and added a new Keyword using an
       HDU::addKey function, in which case they might have specified other types for U.)  
       To avoid compilation errors, the user should generally try to provide a <i>val</i>
       of type T = type U, though there is some flexibility here as the following conversions
       are handled:

       <TABLE BORDER=0>
         <tr><td><b>T</b> (to val)</td><td><b>U</b> (from Keyword obj)</td></tr>
         <tr><td>float</td><td>double (will lose precision), float, int, integer string</td></tr>
         <tr><td>double</td><td>double, float, int, integer string</td></tr>
         <tr><td>int</td><td>int, integer string</td></tr>
       </TABLE>
       More conversions may be added in the future as the need arises.

*/

/*!  \fn template <typename T> void Keyword::setValue(const T& newValue)
       \brief modify the value of an existing Keyword and write it to the file

       \param newValue (T) New value for the Keyword

       <b>Allowed T types:</b> This must copy <i>newValue</i> to a data member of type U in the
       Keyword subclass <b>KeyData<U></b> (see description for Keyword::value (T& val) for more
       details).  To avoid compilation errors, it is generally best to provide a <i>newValue</i>
       of type T = type U, though the following type conversions will also be handled:

       <TABLE BORDER=0>
          <tr><td><b>T</b> (from newValue)</td><td><b>U</b> (to Keyword obj)</td></tr>
          <tr><td>float</td><td>double, float</td></tr>
          <tr><td>double</td><td>double, float (will lose precision)</td></tr>
          <tr><td>int</td><td>double, float, int, integer string</td></tr>
