Tera Introspection

This crate provides a way to introspect a Tera template. The major code src/parser is directly copied from Tera. The only new code is in src/introspection. As this is something just for me to learn how the AST of the Tera template works, and the introspection is pretty hacky, I don't think it is good to contribute the code back to the Tera project.
