If you look closely at the source code generated by the Tool for your
parser --- and it is one of the strengths of ANTLR that you can actually
read and debug the generated code --- you will see that each Parser in
your grammar has a corresponding method in the generated source code.
And that method has a return type of a structure one of whose fields is
`tree`, the AST generated by that rule.

Hope this helps...
