 """Convert parse tree to AST.
 
 This module converts the parse tree to the AST we use for code generation. The
 main entry point is OrderedModule, which gets passed the parser
 representation of a mojom file. When called it's assumed that all imports have
 already been parsed and converted to ASTs before.
