A function added by the New Vegas Script Extender.
Returns the index of an object in a form list. If the object is contained in the list exactly, this index is returned, otherwise if the base form or a leveled form of the object is contained, this index is returned. If the object is not contained in the list in either reference, base, or leveled form, the constant -1 is returned.
