Adjusted WALD-T method of CI estimation

1 | ```
ciATW(n, alp, h)
``` |

`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 approximate method based on a t_approximation of
the standardized point estimator for all *x = 0, 1, 2 ..n.*

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

`LATW ` |

`UATW ` |
Adjusted WALD-T Upper Limit |

`LABB ` |
Adjusted WALD-T Lower Abberation |

`UABB ` |
Adjusted WALD-T Upper Abberation |

`ZWI ` |

`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.
