syntax: Note that files don't have to use Unix new lines ...

They also don't have to be normalized.

tokenize: Support CR LF new line sequences

tokenize: Add more new line symbols

parse: Ignore whitespace in text, instead join words with spaces ...

This cuts down on complexity as now only the tokenizer deals with
whitespace and makes whitespace no longer a factor in the language.

docs: Bump copyright

.gitignore: Hide all __pycache__ directories

make: Remove pytest and mutmut cache

syntax: Drop NewLang version keyword ...

Bundling NewLang solves the issue of version compatibility.

syntax: Drop support for shebangs ...

Shebangs are useful for writing scripts, but they assume an install of
NewLang separate from the application.

I don't plan to support that, only bundling of NewLang and its scripts.

docs: Clarify that we mean code points, not characters

syntax: Rename SyntaxLocation's column to offset ...

We don't know anything about columns or displaying the code points in
our source file, so be clear it's an offset and not a column.

tests: parse: Add helper insert_random function ...

This is just to help clean up some complicated looking code.

tests: parse: Document draw_token_by_value

syntax: Re-organize file

tests: syntax: Rename draw_token_location to draw_syntax_location

tests: tokenize: Move syntax tests to new file

tokenize: Move syntax to its own module

tests: parse: Add draw_token_by_value function

parse: Add read_token function

tests: parse: Move syntax tests to tokenize ...

This helps with mutmut.

tests: tokenize: Remove reference to NEWLINE

tests: tokenize: Draw classified tokens for testing locations ...

This way things are actually likely to draw newlines.

tests: parse: Remove unused code

tokenize: Remove unused list of keywords

parse: Move Syntax to tokenize and replace Token ...

These are basically the same classes so merge them

parse: Don't nest tokens in values ...

Now that we don't need to copy the TokenType we can just copy the value
directly.

tokenize: Remove TokenType enum ...

In practice this wasn't used: The parse code always checks the value AND
the type. So just check the value only.

tests: parse: Test that parse_text fails with extra StartText tokens

tests: parse: Test invalid content

tests: parse: Draw text syntax tokens ...

This requires fixing a bug for comparing values of different types.
