Hello everyone,

I would like to propose the addition of a non-parametric test for 
quantiles.

Essentially, it as the median analog of a one-sample t-test: just as 
`ttest_1samp` tests whether the population mean is a specified value and 
the result object has a method for computing the confidence interval of 
the population mean, this new function (simply named `quantile_test`) 
tests whether the median is a specified value and the result object has 
a method for computing the confidence interval of the population median.

Differences are:
- it works for any quantile (not just the median)
- it is non-parametric.

Huge thanks to Matt who did all the heavy lifting to help putting this 
PR in shape!
