R function quantile()

[jmaccherone]

Function that allows you to specify where to cut the data. Takes 2 parameters - data source and at which percentages to show cuts.
quantile(SampleMeans, probs=c(0.15, 0.85))
to show quartiles, would be
quantile(SampleMeans, probs=c(0.25, 0.5, 0.75)).

This is just like Issue #40, except instead of hard coding p50, we will put in whatever the user provides.
