++   The following code differs from vanilla NTL
++
++   We add a SetErrorCallbackFunction(). This sets a global callback function _function_,
++   which gets called with parameter _context_ and an error message string whenever Error()
++   gets called.
++
++   Note that if the custom error handler *returns*, then NTL will dump the error message
++   back to stderr and abort() as it habitually does.
