Augments an existing Latin Hypercube Sample, adding points to the design, while
maintaining the *latin* properties of the design. This function then uses the
columnwise pairwise (CP) algoritm to optimize the design. The original design
is not necessarily maintained.

`seed` |
The number of partitions (simulations or design points) |

`m` |
The number of additional points to add to matrix |

`maxSweeps` |
The maximum number of times the CP algorithm is applied to all the columns. |

`eps` |
The optimal stopping criterion |

`verbose` |
