A function to calculate credible intervals and make a table. See page 169.
t_ci_table(coefs,cov.mat,level=0.95,degrees=Inf,quantiles=c(0.025,0.500,0.975))
quantile.mat matrix of quantiles
vector of coefficient estimates, usually posterior means
variance-covariance matrix
desired coverage level
degrees of freedom parameter for students-t distribution assumption
vector of desired CDF points (quantiles) to return
