NYCPHP Meetup

[Malcolm, Gary]

an aside...

	a binary tree is a specific example of a btree... one that can have
up to 2 branches from each node. A generalized btree can have N branches
from a given node. The search depth of an N branch btree (how may nodes to
check b4 you get your info) can give definite advantages if an application
can suck up big bunches of information at any given iteration (example:
reading from disk).  

I agree that a btree is a pretty good solution to the big bunches of files
problem but the very best implementations are already done for us (in db's)
