This grammar is a collection of the different modules. It differs from `Lang` in two main ways:

- the combinations in Noun, Verb, Adjective, Adverb, Sentence are not included
- instead, Symbol and Predication are used

In practice, the most important difference is that only present-tense sentences are included, and that symbolic expressions are recognized as NPs.
