* Remove extra attributes for elimination rules, unneeded for now.Josh Chen2018-07-061-2/+1

* Added attributes to type elimination rules, not sure if these will actually ↵Josh Chen2018-07-061-0/+2
| | | | be needed or useful later. Added [comp] attribute to be used by simplification met methods.
* Trivial changesJosh Chen2018-07-041-1/+1

* Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵Josh Chen2018-07-031-2/+1
| | | | powerful derive method. Used these to rewrite proofs.
* Proving path composition. Need to set up the Simplifier to simplify ↵Josh Chen2018-06-301-0/+1
| | | | application of object-lambdas to arguments.
* Finished proofs of projectionsJosh Chen2018-06-301-1/+1

* Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵Josh Chen2018-06-181-5/+13
| | | | Added type formation rules expressing necessity of the conditions.
* Removed all [simp] attributes, these will be added later when I set up the ↵Josh Chen2018-06-181-12/+19

* Decided on a new proper scheme for type rules using the idea of implicit ↵Josh Chen2018-06-171-1/+1
| | | | well-formed contexts and guaranteed conclusion well-formedness. Product type rules now follow this scheme.
* Type rules now have \"all\" premises explicitly stated, matching the ↵Josh Chen2018-06-121-6/+13

* Reorganize codeJosh Chen2018-06-091-0/+48
