Say, we have rule "a? b? c". Now we parse "ac" and "bc". HOW I can determine 
which optional part was specified? In 'results' array in both cases will be two 
items. Detecting by Text? No way, text can be too big and strictly speaking 
should not be involved in this procedure.
Any suggestions?

"Type 'Writer' already defines a member called 'DoReferencesLocal' with the 
same parameter types".

please, make error format like visual studio: <file>(<line>,<col>): error 
<Tool-short-name><error-number>: <error-message>
example:
UbbParser.peg(7,20): error Peg1: Expected whitespace or identifier or comment

With this error format Visual Studio allowed quick go to error place in 
peg-file.

File "WriteNonTerminal.cs" is missing in repository.

In file "Writer.cs" there is reference to "TemplateEngine" class, but no such 
class found.
