Remarks
Parses LES (Loyc Expression Syntax) code into a sequence of Loyc trees (LNode), one per top-level statement.
You can use Les2LanguageService.Value with ParsingService.Parse to easily parse a text string (holding zero or more LES statements) into a Loyc tree.
This class expects to receive tokens from Les2Lexer that have been preprocessed by TokensToTree, with whitespace tokens filtered out.
