Price options according to the famous Black-Scholes formula, with the optional addition of a jump-to-default intensity and discrete dividends.

1 2 | ```
blackscholes(callput, S0, K, r, time, vola, default_intensity = 0,
divrate = 0, borrow_cost = 0, dividends = NULL)
``` |

`callput` |
1 for calls, -1 for puts |

`S0` |
initial underlying price |

`K` |
strike |

`r` |
risk-free interest rate |

`time` |
Time from |

`vola` |
Default-free volatility of the underlying |

`default_intensity` |
hazard rate of underlying default |

`divrate` |
A continuous rate for dividends and other cashflows such as foreign interest rates |

`borrow_cost` |
A continuous rate for stock borrow costs |

`dividends` |
A |

Note that if the `default_intensity`

is set larger than zero then
put-call parity still holds. Greeks are reduced according to cumulated default
probability.

All inputs must either be scalars or have the same nonscalar shape.
