This is a wrapper function to call the C routines for the scan statistic to refine current candidate segmentations computing from the IGS

1 2 | ```
ScanStatRefineComp(combZCumSum, combXCumSum, combZPoint, combXPoint,
p, nTotal, grid.cur, grid.LR, max.win, statistic)
``` |

`combZCumSum` |
A cumulative sum of the number of case reads |

`combXCumSum` |
A cumulative sum of the number of reads |

`combZPoint` |
The number of case reads at the grid points |

`combXPoint` |
The number of reads at the grid points |

`p` |
The proportion of case reads in the current region |

`nTotal` |
The total number of reads in the current region |

`grid.cur` |
The current grid to be computed on |

`grid.LR` |
The left and right limits of the existing candidate segmentations that will be refined, indexed by the current grid |

`max.win` |
The maximum inter-window to be considered for new scan |

`statistic` |
The type of statistic. Can be 'binomial','rabinowitz' or 'normal'. |

The computations are done in C for speed. The three types of statistics are by the use of exact binomial likelihood ('binomial'), score statistic ('rabinowitz') or using normal approximation to the binomial ('normal').

Returns a matrix containing the refined candidate change points
