2018-08-07	Old application syntax incompatible with Eisbach	Josh Chen	1	-14/+14

2018-08-07	Experiment with polymorphic dependent eliminators, i.e. we leave type and ↵	Josh Chen	1	-9/+9
	type family decorations implicit.
2018-08-06	Partway through changing function application syntax style.	Josh Chen	1	-7/+9

2018-08-04	Reorganize theories	Josh Chen	1	-18/+21

2018-07-12	Unit and Null types. Methods.	Josh Chen	1	-0/+13

2018-07-11	Universes implemented. Type rules modified accordingly. No more automatic ↵	Josh Chen	1	-16/+8
	derivation of "A:U" from "a:A".
2018-07-07	Library snapshot. Methods written, everything nicely organized.	Josh Chen	1	-1/+2

2018-07-06	Remove extra attributes for elimination rules, unneeded for now.	Josh Chen	1	-1/+0

2018-07-06	Added attributes to type elimination rules, not sure if these will actually ↵	Josh Chen	1	-0/+2
	be needed or useful later. Added [comp] attribute to be used by simplification met methods.
2018-07-04	Trivial changes	Josh Chen	1	-6/+7

2018-07-03	Refactor HoTT_Methods.thy, proved more stuff with new methods.	Josh Chen	1	-4/+4

2018-07-03	Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵	Josh Chen	1	-1/+1
	powerful derive method. Used these to rewrite proofs.
2018-06-30	Add Pair_intro	Josh Chen	1	-0/+7

2018-06-27	Move projection function definitions out of Sum.thy	Josh Chen	1	-170/+1

2018-06-18	Dependent projection properties done.	Josh Chen	1	-27/+58

2018-06-18	Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵	Josh Chen	1	-16/+81
	Added type formation rules expressing necessity of the conditions.
2018-06-18	Removed all [simp] attributes, these will be added later when I set up the ↵	Josh Chen	1	-18/+31
	simplifier. Proved simplification rule for dependent fst.
2018-06-17	Proof of projection functions now harder. Should look up automation methods.	Josh Chen	1	-8/+14

2018-06-17	Eliminators must be completely parametrized at the meta-level.	Josh Chen	1	-14/+5

2018-06-15	projections	Josh Chen	1	-13/+28

2018-06-12	Type rules now have \"all\" premises explicitly stated, matching the ↵	Josh Chen	1	-31/+62
	formulation in the HoTT book.
2018-06-09	Reorganize code	Josh Chen	1	-0/+78
