Calculates the minimum spanning tree distance, in kilometers, using Prim's Algorithm [1] and a previously calculated pairwsie distance matrix

1 | ```
MSTDist_FromMat(longs, lats, DistMat)
``` |

`longs` |
- Longitudinal occurrences in decimal degrees |

`lats` |
- Latitudinal occurrences in decimal degrees |

`DistMat` |
- Pairwsie distance matrix of coordinates, from the PWMatrix() function |

Uses Prim's algorithm for finding the minimum spanning tree

Returns the minimum spanning tree distance in kilometers, the pairwise distance matrix of occurrences, the order points were connected in, and a 2-column array of coordinates
