For C#, you have to prefix the Tokens with the xxxTokenTypes class 
name. C# interfaces cannot contain constants like in Java and there 
is no support for global identifiers like in C++.

It's better to get used to using the "TokenTypes.OR" style. This is 
how things will be done with C#. Study the CSharp examples for more 
info....
