Exact method of CI estimation

1 | ```
ciEXx(x, n, alp, e)
``` |

`x` |
- Number of sucess |

`n` |
- Number of trials |

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

`e` |
- Exact method indicator in [0, 1] 1: Clopper Pearson, 0.5: Mid P |

Confidence interval for `p`

(for the given `x`

and `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.*

A dataframe with

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

`LEXx ` |
- Exact Lower limit |

`UEXx ` |
- Exact Upper Limit |

`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.
