\| \| \| \|	not need to worry about preconditions)
*	Prod.thy now has the correct definitional equality structure rule. ↵	Josh Chen	2018-08-16	1	-17/+11
\| \| \| \|	Definition of function composition and properties.
*	Rename to distinguish function and path composition; function composition ↵	Josh Chen	2018-08-15	1	-8/+18
\| \| \| \|	proofs, which have issues...
*	Basic compute method	Josh Chen	2018-08-15	1	-1/+1
\|
*	Tweak proof methods, some type rules; add HoTT Book examples	Josh Chen	2018-08-15	1	-1/+1
\|
*	Function composition, rename path composition to differentiate the two.	Josh Chen	2018-08-15	1	-0/+16
\|
*	rcompose done	Josh Chen	2018-08-13	1	-14/+8
\|
*	Commit before testing polymorphic equality eliminator	Josh Chen	2018-08-12	1	-10/+12
\|
*	Old application syntax incompatible with Eisbach	Josh Chen	2018-08-07	1	-6/+6
\|
*	Experiment with polymorphic dependent eliminators, i.e. we leave type and ↵	Josh Chen	2018-08-07	1	-5/+5
\| \| \| \|	type family decorations implicit.
*	Partway through changing function application syntax style.	Josh Chen	2018-08-06	1	-17/+17
\|
*	Reorganize theories	Josh Chen	2018-08-04	1	-26/+30
\|
*	Unit and Null types. Methods.	Josh Chen	2018-07-12	1	-0/+19
\|
*	Universes implemented. Type rules modified accordingly. No more automatic ↵	Josh Chen	2018-07-11	1	-4/+4
\| \| \| \|	derivation of "A:U" from "a:A".
*	Library snapshot. Methods written, everything nicely organized.	Josh Chen	2018-07-07	1	-0/+1
\|
*	Remove extra attributes for elimination rules, unneeded for now.	Josh Chen	2018-07-06	1	-2/+1
\|
*	Added attributes to type elimination rules, not sure if these will actually ↵	Josh Chen	2018-07-06	1	-0/+2
\| \| \| \|	be needed or useful later. Added [comp] attribute to be used by simplification met methods.
*	Trivial changes	Josh Chen	2018-07-04	1	-1/+1
\|
*	Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵	Josh Chen	2018-07-03	1	-2/+1
\| \| \| \|	powerful derive method. Used these to rewrite proofs.
*	Proving path composition. Need to set up the Simplifier to simplify ↵	Josh Chen	2018-06-30	1	-0/+1
\| \| \| \|	application of object-lambdas to arguments.
*	Finished proofs of projections	Josh Chen	2018-06-30	1	-1/+1
\|
*	Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵	Josh Chen	2018-06-18	1	-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 Chen	2018-06-18	1	-12/+19
\| \| \| \|	simplifier. Proved simplification rule for dependent fst.
*	Decided on a new proper scheme for type rules using the idea of implicit ↵	Josh Chen	2018-06-17	1	-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 Chen	2018-06-12	1	-6/+13
\| \| \| \|	formulation in the HoTT book.
*	Reorganize code	Josh Chen	2018-06-09	1	-0/+48
