Function SCIPcreateConsDisjunction 

pub unsafe extern "C" fn SCIPcreateConsDisjunction(
    scip: *mut SCIP,
    cons: *mut *mut SCIP_CONS,
    name: *const c_char,
    nconss: c_int,
    conss: *mut *mut SCIP_CONS,
    relaxcons: *mut SCIP_CONS,
    initial: c_uint,
    enforce: c_uint,
    check: c_uint,
    local: c_uint,
    modifiable: c_uint,
    dynamic: c_uint,
) -> SCIP_RETCODE

creates and captures a disjunction constraint

@note the constraint gets captured, hence at one point you have to release it using the method SCIPreleaseCons()
