Tries to compute the maximum likelihood tree model for a given data set through stepwise leaf insertion and rearrangements.

1 | ```
MLtopology(x, verbose = FALSE)
``` |

`x` |
a binary matrix with rows representing tumors and columns representing genetic alterations. |

`verbose` |
a Boolean value indicating whether intermediate results of the algorithm are to be printed. |

A list with the following components:

`tree` |
the resulting tree in matrix format. |

`p` |
a vector of the maximum likelihood edge parameters (model probabilities). |

`totloglik` |
the log-likelihood of the tree model. |

`var.names` |
the character vector with the names of alterations. |

`newick` |
the tree model in Newick format. |
