Function to find points along a horseshoe shape

1 | ```
PtsAlgHorseShoe(z, spacing = 1, endAngles = c(-90, 90))
``` |

`z` |
- Distance in kilometers from the center of the horseshoe to its lower boundary |

`spacing` |
- Degrees between successive point outlining the horseshoe shape |

`endAngles` |
- Array of values denoting the degree of rotation for the circular part of the horseshoe distribution |

Currently forces use 0,0 as the center, a height 5/4 width, and r2=2*r1 of origin (center)

Returns a 2-dimensional array of decimal degree coordinates outlining a horseshoe shape

Currently only works when endAngles are multiples of -90,90; otherwise rectangle point positions are off
