Exact method of CI estimation

1 | ```
ciEX(n, alp, e)
``` |

`n` |
- Number of trials |

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

`e` |
- Exact method indicator in [0, 1] 1: Clopper Pearson, 0.5: Mid P, The input can also be a range of values between 0 and 1. |

Confidence interval for `p`

(for all `x`

= 0, 1, 2 ..`n`

),
based on inverting
equal-tailed binomial tests with null hypothesis

*H0: p = p0*

and calculated from the cumulative binomial distribution. Exact two sided P-value is usually calculated as

*P= 2[e*Pr(X = x) + min{(Pr(X < x), Pr(X > x))}]*

where
probabilities are found at null value of p and *0 <= e <= 1*.
The Confidence Interval of `n`

given `alp`

along with lower and upper abberation.

A dataframe with

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

`LEX ` |
- Exact Lower limit |

`UEX ` |
- Exact Upper Limit |

`LABB ` |
- Likelihood Ratio Lower Abberation |

`UABB ` |
- Likelihood Ratio Upper Abberation |

`ZWI ` |
- Zero Width Interval |

`e ` |
- Exact method input |

`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.
