debug_info - Print some internal information
mixed debug_info(int i,mixed o)
This is supposed to be a general function for getting inside driver
debug information but so far it can only print a lot of stuff about
objects and it doesn't return anything sensible. The integer i can
so far only be the values 0 or 1 it decides what information to print.
The mixed argument o is for these values of i supposed to be the
object to print information about.
