tests: lexer: Include token type in equality comparison ...

Oops! Found this bug with mutation testing, not by review.

tests: lexer: Split up soup functions and valid token testing ...

This will help when we add error injection

tests: lexer: Re-order draw_token_lexer inner loop ...

Hopefully this makes more sense.

tests: Remove dead code and re-order lexer tests

tests: Randomize soup filename

tests: Use curr_line and curr_column for EOF

tests: Move lexer token equality check to __eq__ method

tests: Move EOF to lexer soup generator

tests: Check EOF location

tests: Check lexer token locations

tests: Use word salad for shebang generator

tests: Move whitespace joining to its own function

tests: Use a word salad for text and notes

tests: Refactor whitespace drawing in to its own function

tests: Draw interesting identifiers for symbols

tests: Document and refactor SampleToken ...

This makes it clearer what it is and how to have tokens that the lexer
eats

tests: Add empty token to lexer

tests: Add shebangs to lexer soup

tests: Move notes to lexer soup

tests: Remove unused draw_token_reserved

tests: Remove conjoined tokens ...

These aren't tokens, these are just different named symbols I think.

tests: Generate a lexer token soup ...

At the moment this doesn't include location information, but this is a
good first step.

tests: Make test_lexer_token test conjoined tokens

tests: Generate conjoined tokens from symbols too

tests: Add True and False to reserved_words

parse: Strip whitespace in text tokens

parse: Replace 'Begin' with 'Start' in keywords ...

Okay, it's to the point I'm writing bugs in tests due to this.
Just change it already.

tests: Rename 'text_tokens' to 'note_tokens'

tests: Wrap tokenizer to catch parse errors

tests: Re-order parser tests
