        Merges two maps. If a value already exists for a given key in a resulting map
        then the mergeFunction is used to resolve the issue.
        Parameters:
        firstMap - the Map to merge
        secondMap - the Map to merge
        mergeFunction - the function used to resolve conflict for the same key
        Returns:
        the Map
