Function statement_from_content 

pub fn statement_from_content(
    catalog: &Catalog,
    node: &Value,
) -> Result<Statement, StatementContentError>

Convert one rule-content-v1 statement into the public model.

catalog decides which ids exist and how many arguments they take. The result is not validated as a program: whether the statement fits its rule (an If without its End, a value of the wrong type) is for canonical validation of the edited program.
