Trims curves to specified range of X and Y coordinates

1 2 | ```
phylocurve.trim(phylocurve.generalized, min_Y = -Inf,
max_Y = Inf, min_X = -Inf, max_X = Inf)
``` |

`phylocurve.generalized` |
The value returned by the phylocurve.generalized function |

`min_Y` |
The minimum Y value for trimming curves |

`max_Y` |
The maximum Y value for trimming curves |

`min_X` |
The minimum X value for trimming curves |

`max_X` |
The maximum X value for trimming curves |

`aligned_data ` |
x and y coordinates arranged in a single row vector for each species |

`aligned_coordinates ` |
x and y coordinates for each species (one data point per row) |

`aligned_X` |
Aligned X coordinates in N x M matrix |

`aligned_Y` |
Aligned Y coordinates in N x M matrix |

`nr` |
Number of aligned landmarks |

`anc_X` |
Vector of root X values (assuming Brownian motion) |

`anc_Y` |
Vector of root Y values (assuming Brownian motion) |

`tree` |
Phylogenetic tree supplied into the function |
