/*

By default we do not translate exceptions for EVERY C++ function since not every
C++ function throws, and that would be unused and very bulky mapping code.
Therefore please help gather the subset of C++ functions for each class that do
throw and add each in a separate HANDLE_EXCEPTIONS() invocation before its
respective class declaration.  i.e. put them inside of their respective *.i
file near the top; only class BOARD functions go in board.i.
