Calculates Angles for determining ternary distribution of faults based on P-T axis orientation.

1 | ```
Bfocvec(Paz, Pdip, Taz, Tdip)
``` |

`Paz` |
vector of azimuths, degrees |

`Pdip` |
vector of dips, degrees |

`Taz` |
vector of azimuths, degrees |

`Tdip` |
vector of dips, degrees |

This calculation is based on Froelich's paper.

LIST:

`Bdip ` |
azimuths, degrees |

`Baz` |
dips, degrees |
