2023-10-31	asm/main logs are now indented and look prettier	Aryadev Chavali

2023-10-31	Lexer now returns errors on failure	Aryadev Chavali
	Currently only for invalid character literals, but still a possible problem.
2023-10-31	parse_word deals with characters now	Aryadev Chavali
	Just takes the character literally as a number.
2023-10-31	Changed asm/parser instruction push-reg->push.reg	Aryadev Chavali

2023-10-29	Added a "usage" message and colours for assembler	Aryadev Chavali
	Prints useful and pretty messages when verbose being at least 1.
2023-10-28	Introduce error reporting in asm/main	Aryadev Chavali
	Pretty simple implementation, I've stopped printing the tokens cos I think the lexer is done.
2023-10-28	asm/parser supports all opcodes, introduced parse errors	Aryadev Chavali
	Introduced some functions to parse differing types of opcodes. Use the same style of a.b.c... for namespacing or type specification for certain opcodes. Bit hacky and not tested, but does work. Parse errors can be reported with an exact location using the token column, line.
2023-10-28	Ignore comments (using semicolons) in lexer	Aryadev Chavali
	Easier to do it here than at the parser.
2023-10-28	Introduced a column and line for each token	Aryadev Chavali
	Accurate error reporting can be introduced using this.
2023-10-26	Plugged in asm/parser to asm/main	Aryadev Chavali
	Just prints instructions so far.
2023-10-26	Implemented a rudimentary parser with support for 4 instruction types	Aryadev Chavali

2023-10-26	Added support in lexer for negative numbers	Aryadev Chavali
	Though we deal with unsigned numbers internally, it should be possible to read and manipulate negative numbers through 2s complement. Later on we'll add support for signed operations via 2s complement, so this should be allowed.
2023-10-26	asm/main now uses TOKEN_STREAM_AT	Aryadev Chavali

2023-10-26	Lexer forces uppercase for symbols	Aryadev Chavali

2023-10-26	Auto fill licenses	Aryadev Chavali

2023-10-26	Unified literal for numbers, main program now tokenises	Aryadev Chavali

2023-10-25	Started working on a parser	Aryadev Chavali
	No implementations yet
2023-10-25	Separated lexer from main file in asm	Aryadev Chavali

2023-10-24	Wrote lexer for assembly	Aryadev Chavali
	Pretty simple tokeniser, doesn't do a lot and needs to error check better.
2023-10-23	Starting development on assembly language	Aryadev Chavali
