is defined as unsigned char 0x01, will clear wking. See the
definition of DETAIL_CASTLING and castling_prohibited_table[].

/* Some project notes */
/*====================*/
/****************************************************************************
* Class Hierarchy:
*
* The Chess classes are intended to provide a reusable chess subsystem. To
* understand the hierarchy of classes, think in terms of the Java concept
* of derived classes "extending" base classes.
*
* So
* ChessPositionRaw
* ;A simple C style structure that holds a chess position
* ChessPosition extends ChessPositionRaw
* ;ChessPosition adds constructors, and other simple facilities
* ChessRules extends ChessPosition
* ;ChessRules adds all the rules of standard chess
* ChessEvaluation extends ChessRules
* ;ChessEvaluation is a simple scoring function for a chess engine
* ;it attempts to calculate a score (more +ve numbers for better white
* ;positions, more -ve numbers for better black positions) for a
* ;position. Tarrasch GUI uses this only to attempt to list the most
* ;plausible moves first when you click on a square that can receive
* ;multiple moves
* ChessEngine extends ChessEvaluation
* ;ChessEngine adds a search tree to ChessEvaluation to make a
* ;complete simple engine (the Tarrasch Toy Engine)
* ;ChessEngine is now split off from the rest of the thc chess library
* ;and is part of the Tarrasch Toy Engine project instead
****************************************************************************/
/****************************************************************************
* Explanation of namespace thc:
*
* The Chess classes use the C++ namespace facility to ensure they can be
* used without name conflicts with other 3rd party code. A short, but
* highly likely to be unique namespace name is best, we choose "thc" which
* is short for TripleHappyChess.
