FUNCTION

NAME
        add_sp - change the spell points of a living object


LOCATION
	/obj/living_functions.c

SYNTAX
	varargs int add_sp(int amount [, ignore_flag])

DESCRIPTION
	With this function you can add an amount, positive or negative, to
        a living's spell points. Checks on limits can be turned off by using
        the ignore flag. The use of the ignore flag is logged. The function
        returns the living object's number of spell points after it 
        completes.


NOTE
	There is no check if the spell points are reduced below zero.


NOTE
	This could be used to heal spell points alone (as opposed to
	heal_self(L) which heals hit points and spell points together).


NOTE
	With the ignore flag, this can be used to raise a living object above
	its maximum normal spell point range.  This must be approved.
