add #%type annotation; add type->str; type constructor pattern match
...
- #%type annotation distinguishes types from terms
- is-type? checks #%type
- type->str fixes type printing
- wasnt recursively calling get-orig
- use delay in "type" syntax-class norm attribute
- fixes eager eval problem from before
- add more invalid type tests
- only tested up to stlc+lit.rkt
- nicer type constructors
- more concise, intuitive pat matching language
- use for-meta 2 macros
