Function is_binding_contract 

pub fn is_binding_contract(
    stipulated: bool,
    accepted: bool,
    offeror: CapacityStatus,
    acceptor: CapacityStatus,
) -> bool

A contract is binding iff it was stipulated, assented to, AND both parties had intact juridical capacity (composes capacity::stipulation_binding — an agreement assented to under duress or by an incapacitated party does not bind).
