	Definition of function composition and properties.
2018-08-14	Well-formation rules are back in the methods; new theory synthesizing the ↵	Josh Chen	1	-1/+1
	natural number predecessor function.

2018-07-12	Unit and Null types. Methods.	Josh Chen	1	-1/+2

2018-07-11	Universes implemented. Type rules modified accordingly. No more automatic ↵	Josh Chen	1	-23/+12
	derivation of "A:U" from "a:A".

2018-07-07	Library snapshot. Methods written, everything nicely organized.	Josh Chen	1	-1/+1

2018-07-06	Added attributes to type elimination rules, not sure if these will actually ↵	Josh Chen	1	-3/+7
	be needed or useful later. Added [comp] attribute to be used by simplification met methods.
2018-07-03	Refactor HoTT_Methods.thy, proved more stuff with new methods.	Josh Chen	1	-1/+3

2018-07-03	Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵	Josh Chen	1	-4/+5
	powerful derive method. Used these to rewrite proofs.
2018-06-27	Library organization and formatting	Josh Chen	1	-1/+3

2018-06-18	Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵	Josh Chen	1	-2/+1
	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	-1/+1
	simplifier. Proved simplification rule for dependent fst.
2018-06-17	Proof of projection functions now harder. Should look up automation methods.	Josh Chen	1	-1/+1
