Retrieve metadata directly for multiple series at once

[GitHunter0]

Hey @RaymondMcT , @daroczig , @ccleung, is there a way to retrieve metadata directly without having to first retrieve the data via Quandl() like this?

library(Quandl)
library(tidyverse)
Quandl(c('ODA/PLEAD_USD'), meta=TRUE) %>%
  metaData()

Also, is it possible to retrieve multiple metadata at once? Because if I do this, the result is NULL

Quandl(c('ODA/PLEAD_USD', 'ODA/PALUM_USD'), meta=TRUE) %>%
   metaData()

Those features would make my pipeline much cleaner. I appreciate any feedback. Quandl is a fantastic package.
