Adjusted Wald method of CI estimation

1 | ```
ciAWDx(x, n, alp, h)
``` |

`x` |
- Number of successes |

`n` |
- Number of trials |

`alp` |
- Alpha value (significance level required) |

`h` |
- Adding factor |

Given data `x`

and `n`

are modified as *x + h* and *n + (2*h)*
respectively, where *h > 0* then Wald-type interval is applied for the given `x`

and `n`

.

A dataframe with

`x` |
Number of successes (positive samples) |

`LAWDx ` |
Adjusted Wald Lower limit |

`UAWDx ` |
Adjusted Wald Upper Limit |

`LABB ` |
Adjusted Wald Lower Abberation |

`UABB ` |
Adjusted Wald Upper Abberation |

`ZWI ` |
Zero Width Interval |

`prop.test and binom.test`

for equivalent base Stats R functionality,
`binom.confint`

provides similar functionality for 11 methods,
`wald2ci`

which provides multiple functions for CI calculation ,
`binom.blaker.limits`

which calculates Blaker CI which is not covered here and
`propCI`

which provides similar functionality.
