This function provides an alternative way to optimize the projection index, by moving along a geodesic path.

1 | ```
search_geodesic(current, alpha = 1, index, max.tries = 5, n = 5)
``` |

`current` |
The starting projection. |

`alpha` |
Maximum distance to travel (currently ignored). |

`index` |
The projection index. |

`max.tries` |
Maximum number of failed attempts before giving up. |

`n` |
Number of random steps to take to find best direction. |

The function `search_geodesic`

finds only one basis at a time. The `caller`

is a wrapper function that calls `search_geodesic`

`bases`

number of times.

Returns the basis found.

The function has been copied as is from the `tourr`

package.
