See the isar-ref manual about method_setup for some clues on this slightly 
cumbersome task.  Isar does not provide a separate language for definining 
proof methods, everything needs to be done by hand via low-level ML

In that case, there is probably no need to define new methods at all, 
since most existing methods already do the right thing.  E.g. use simp_all 
for ALLGOALS asm_full_simp_tac, or blast+ for ALLGOALS blast_tac.  Also 
note that various tactic emulation methods (e.g. rule_tac) provide 
explicit syntax for addressing goal ranges (again see the isar-ref
