You have to move the spot from outside the class. See for instance
EuropeanOption::testGreeks() in test-suite/europeanoption.cpp; you can
look at the part where the "expected" map is filled.

This said, as Simon mentioned, you'll have to be careful of numerical
artifacts in the results if you're using Monte Carlo.
