Generic debug class
Other modules can always define extra debug flags for local usage, as long as
they make sure they append them to debug_flags
Also its always a good thing to prefix local flags with something, to reduce risk
of coliding flags. Nothing breaks if two flags would be identical, but it might
activate unintended debugging.
flags can be numeric, but that makes analysing harder, on creation its
not obvious what is activated, and when flag_show is given, output isnt
really meaningfull.
This Debug class can either be initialized and used on app level, or used independantly
by the individual classes.
For samples of usage, see samples subdir in distro source, and selftest
in this code

"""
Define your flags in yor modules like this:
from debug import *
DBG_INIT = 'init' ; debug_flags.append( DBG_INIT )
DBG_CONNECTION = 'connection' ; debug_flags.append( DBG_CONNECTION )
The reason for having a double statement wis so we can validate params
and catch all undefined debug flags
This gives us control over all used flags, and makes it easier to allow
global debugging in your code, just do something like
foo = Debug( debug_flags )
group flags, that is a flag in it self containing multiple flags should be
defined without the debug_flags.append() sequence, since the parts are already
in the list, also they must of course be defined after the flags they depend on ;)
example:
DBG_MULTI = [ DBG_INIT, DBG_CONNECTION ]
NoDebug
-------
To speed code up, typically for product releases or such
use this class instead if you globaly want to disable debugging
