tests: parse: Draw text syntax tokens ...

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

parse: tests: Clarify errors and tests

tests: parse: Draw classified tokens for better coverage

tests: parse: Mutate StartText/EndText for testing

tests: parse: Test parse_text fails without StartText or EndText

parse: Check token types when parsing text

tests: tokenize: Fix typo

parse: Add parse_text to parse a text syntax node ...

No error handling tests are added yet.

tests: parse: Move test to make more sense

parse: Rename TokenStream to SyntaxStream

parse: Require the caller to copy the TokenStream list ...

This is more Pythonic I think.

parse: Add TokenStream class ...

This will be used for stateful parsing, with lookahead in future.

parse: Don't strip non-token syntax ...

This bug was picked up by mutmut.

parse: Use syntax for strip_whitespace

tests: parse: Add draw_syntax_random

parse: Add import_tokens to import tokens to syntax

parse: Add Syntax node ...

Currently this just holds a token, but will eventually hold parsed
syntax tree values.

tests: parse: Use classified tokens for better coverage

parse: Rename remove_whitespace to strip_whitespace

parse: Add parse wrapper function

parse: Add remove_whitespace pass

make: Remove hypothesis statistics and seed ...

We don't really need these.

make: Remove _build/NewLang when building ...

I'm fairly sure Python alrady does this. Better safe than sorry.

parse: Move to oldparse ...

This is in preparation of writing a new parser.
Once the new parser is ready then this code can be junked.

testss: tokenize: Add documentation on the expected behaviours

tests: tokenize: Give garbled tokens to the classifier ...

This helps prove that the classifier only classifies full tokens, not
substrings.

tokenize: Add shebang types

tokenize: Classify language keywords

tokenize: Add booleans

tokenize: Add is_newline and is_whitespace functions
