%spellRoutineMobTargets()

    This function has specific usefulness within a BlobbieScript used to
    implement a spell. The function makes particular use of variables
    pre-defined for spell BlobbieScripts and is provided to mimic behaviour
    present in the MUD's C source code as provided via #defined MACROS.

    This function is used to generate a list of @targets for a spell. If
    @targets is already defined then it will not try to retrieve them using
    standard methods (pre-defined @targets serves as an override). When
    generating a list of targets the function will take into consideration
    the source of the spell (cast, staff, potion, etc), the area effect of
    the spell (single target, area), and the invoker of the spell (mobile,
    object, room). The function will then retrieve the appropriate list of
    mobiles in the room as perceivable by the invoker. If no targets are
    found then the spell will output the standard "Who will be your
    target?" and either terminate the script or jump execution to a defined
    "spellComplete" jump label. The specific mobiles are determined via the
    following targetting range as might be used for the
    %getTargets() function: "r[m]". Finally, this function accepts two
    %parameters to further determine what targets to generate. The @targetType
    %may be one of the following:

        group
        notGroup
        self

    Anything else will default to the mobiles in the room. Finally, if
    @emptyMeansSelf is set to true then if no targets are given then the spell
    will default to the caster.


    Example:

    %spellRoutineMobTargets( group, 1 );

    Wrong Example:

    @targets = %spellRoutineMobTargets();
