comment some productions in expparse.y
is it really this easy to do qualified inverse attrs right?
attribute_decl comment
update generated parser files
test schema for lost qualifiers - still need to automate the test
use Expression for Unique rules

this changes libexpress only - must change exppp, exp2cxx, exp2python
sync generated files
update exppp to use Expression for Unique rules
reformat a comment
change lost qualifiers test schema to match exppp output formatting exactly
fix compile error with exppp test for long strings
wrong variable name for testing
actually build and test long string test
add test for lost qualifiers on unique rules
use Expression for Unique rules in exp2cxx
in exppp, print inverse attrs as expressions
rename lost_qualifiers.*, modify files accordingly
add exppp test for inverse qualifiers
makes more sense to have these schemas under test/unitary_schemas
clean up a bit
