create a perfectly symmetric version of landmarks

1 | ```
symmetrize(x, pairedLM)
``` |

`x` |
k x m matrix or k x m x n array, with rows containing landmark coordinates |

`pairedLM` |
A X x 2 matrix containing the indices (rownumbers) of the paired LM. E.g. the left column contains the lefthand landmarks, while the right side contains the corresponding right hand landmarks. |

the landmarks are reflected and relabled according to
`pairedLM`

and then rotated and translated onto `x`

.
Both configurations are then averaged to obtain a perfectly symmetric one.
