Wald method of CI estimation

1 | ```
ciWDx(x, n, alp)
``` |

`x` |
- Number of successes |

`n` |
- Number of trials |

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

Wald-type interval that results from inverting
large-sample test and evaluates standard errors at maximum likelihood estimates
for the given `x`

and `n`

A dataframe with

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

`LWDx ` |
Wald Lower limit |

`UWDx ` |
Wald Upper Limit |

`LABB ` |
Wald Lower Abberation |

`UABB ` |
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.
