[Bf-committers] Introduction to Notifiers

[Charles Wardlaw]

Great work, Matt.  Good to know that a system like this exists even if
it currently doesn't have a Python API.

Out of curiosity, how does the 2.5 undo system interface with
Notifiers?  Are microstates still being saved and restored, or is it
now using notifiers to save and restore scene changes by keeping track
of differences in data at a lower level?
