* Prod_comp should have a type constraint. This also fixes a false proof for ↵Josh Chen2018-06-041-14/+38

* Should be final version of Prod. Theorems proving stuff about currying. ↵Josh Chen2018-06-011-19/+50

* New type rules for dependent product and sum.Josh Chen2018-05-301-9/+4

* Fixed dependent product rules, hopefully final now.Josh Chen2018-05-301-72/+27

* More rigorous rules for Product type. Propositions and proofs all working, ↵Josh Chen2018-05-291-12/+55
| | | | but have to think about maybe relaxing the computation rule, or else automating the currying of dependent functions.
* Dependent product rules done and proofs of typing properties so far work. ↵Josh Chen2018-05-281-37/+56
