The pest abstract syntax tree (ast) for a Leo program.

This module contains the Grammar type, a wrapper around the File type in this module. The Grammar type is the datatype generated by the pest parser using grammar from leo.pest. The Grammar type is intended to be parsed into a [Ast]. It should not be parsed by any other pass of the compiler.
