Struct BosonOperatorWrapper

pub struct BosonOperatorWrapper {
    pub internal: BosonOperator,
}

These are representations of systems of bosons.

BosonOperators are characterized by a BosonOperator to represent the hamiltonian of the spin system and an optional number of bosons.

Returns: self: The new BosonSystem with the input number of bosons.
