Introduced a sourcemap for efficient tracing when errors occur. I greatly appreciate @tpronk for his cooperation.

Bug fix

The QuestTrials function can takes the bin size for the second parameter. Even though this parameter is optional, the QuestTrials function did not return the correct results when the parameter was not specified. This bug is solved.
