Wald-T method of CI estimation

1	ciTW(n, alp)

`n`	- Number of trials
`alp`	- Alpha value (significance level required)

An approximate method based on a t_approximation of the standardized point estimator for all x = 0, 1, 2 ..n; that is the point estimator divided by its estimated standard error. Essential boundary modification is when x = 0 or n,

\hat{p}=\frac{(x+2)}{(n+4)}

A dataframe with

`x`	- Number of successes (positive samples)
`LTW`	- Wald-T Lower limit
`UTW`	- Wald-T Upper Limit
`LABB`	- Wald-T Lower Abberation
`UABB`	- Wald-T 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.
