/**
\brief Return a unique identifier for \c t.
The identifier is unique up to structural equality. Thus, two ast nodes
created by the same context and having the same children and same function symbols
have the same identifiers. Ast nodes created in the same context, but having
different children or different functions have different identifiers.
Variables and quantifiers are also assigned different identifiers according to
their structure.
