//! Defines an exception class \a C1 that inherits an exception class \a C2.
/*! \a C2 must be Standard_Failure or its ancestor.
    The macro defines empty constructor, copy constructor and static methods Raise() and NewInstance().
    Since Standard_Failure implements class manipulated by handle, DEFINE_STANDARD_RTTI macro is also
    added to enable RTTI.

    When using DEFINE_STANDARD_EXCEPTION in your code make sure you also insert a macro
    DEFINE_STANDARD_HANDLE(C1,C2) before it.
