I don't think this function offers much to the core but perhaps someone
might find some use in this. I've been using this for a while to
include my models (from my RelationalObjectMapper models) as well as
other non-core includes. When Zend_Cache becomes more stable, usable..
I plan on adding auto class caching functionality to hopefully increase
performance .. if need be.
NOTE: Zend_Config below is my simple parse_ini_file wrapper.
