abstract class with non-virtual destructor
warning about comparison that was always true
_mainRegistry wasn't initialized
default to case insensitive when searching by instance type
functions to look up instance type in file
minor changes to judyLArray.h, judy.c
remove outdated comment from inverse_attr2.cc
doxify comments in classes_misc.c
split a big fprintf up for readability
improve some comments for doxygen
macro CONST -> const
add a FIXME
add variable names to some prototypes in ErrorDescriptor header

include subsuperiterators header
add lazyRefs.h
trivial changes
use lazyRefs in lazyInstMgr
